In 1866, the issue of a five-cent coin made of copper-nickel alloy began. As a result, two coins of the same denomination were simultaneously in circulation - silver half a dime and 5 cents, to which the name "Nickel" has been attached from the first year of issue to the present. The new coins were immediately produced in rather large quantities - 15 million pieces, which is a hundred times more than the more expensive silver coins were issued this year. On the front side of the coin was a symbolic American shield with thirteen stripes, on the back the same number 13 was played up with the number of stars placed around the denomination number.

1867 - 1883 Shield Nickel No Rays - Nickel with a shield, no rays

In 1867, it was decided to somewhat simplify the design of the reverse side, so when minting coins, a lot of marriage was obtained, due to the rays located between the stars. The removal of the separating rays greatly facilitated the production of a new coin from a fairly hard alloy.

1883 - 1913 Liberty Nickel - Nickel with Liberty

Since 1883, on the front side of the Nickel, they began to place the head of Liberty with a diadem surrounded by 13 stars. An image of a wreath with the Roman numeral V appeared on the reverse side. But they “forgot” to put down the designation of the denomination “cents”, as a result, some enterprising Americans began to gild such patches and pass them off as a five-dollar gold coin. The omission with the denomination was corrected in the same year by adding it to the bottom of the coin. The result was two varieties of the 1883 Nickel.

1913 - 1938 Buffalo Nickel - Buffalo Nickel (with bison)

In 1913, the Liberty Head Nickel, which had been in production for thirty years, was replaced by a new design coin, the so-called Buffalo. Renowned sculptor James E. Fraser modeled the image of an Indian head for the obverse, using portraits of three Indian chiefs for this. On the reverse side was placed an impressive-looking American bison, the prototype of which was the 700-kilogram Black Diamond bison living in the New York Zoo.

The coin has two varieties. Initially, the inscription "five cents" was placed simply on the relief under the bison, but since it was quickly erased, a special platform was made for it. Both options are not rare, as 30 million pieces were produced. every.

1938 - 1964 Jefferson Nickel - Jefferson Nickel

In 1938, the Nickel was redesigned again. On the obverse was a portrait of Thomas Jefferson, and on the back of his estate - Monticello.

1942 - 1945 War nickels - War nickels with silver

Part of the dimes, during the Second World War, had a different composition of the coin alloy and are known as "War Nickels". From 1942 to 1945, nickel, which was widely used for military purposes, was replaced by silver in the manufacture of coins. For distinction, coins with silver had a large mint mark on the back - the letters D, S or P.

1965 - 2003 Jefferson Nickel Modern - New Jefferson Nickels

In 1965, the portrait of Jefferson was somewhat reworked, and since 1966, the initials of the medalist began to be placed under the bleed - FS

New Jefferson Nickels

2004 - 2005 Jefferson Nickel Westward Journey - Expedition to the West.

In 2004, the 200th anniversary of the Expedition to the West was widely celebrated in the United States. The Lewis and Clark Expeditions 1804-1806 to the shores of the Pacific Ocean, which was of great importance for the development of the United States and the development of new territories. Since it occurred during the presidency of Thomas Jefferson, it was decided to mark its 200th anniversary with the release of a special commemorative series of four Jefferson Nickels destined for regular currency 2004-2005.

Both 2004 coins featured the standard Jefferson portrait on the obverse, as seen on the 1938-2033 coins. On the reverse side of the first coin there was a plot with the name "Medal of Peace" - a crossed pipe of peace and a tomahawk over folded hands. The second picture was of the Lewis and Clark boat used at the beginning of the expedition.

2004 Expedition to the West - "Peace Medal" and "Boat"

Two of the 2005 coins had a portrait of Thomas Jefferson specially created for them on the obverse side. On the reverse side of one of them was placed an image of an American bison, reminiscent of what was earlier on the Buffalo Nickel (1913-1938). On the second expedition opened a panorama with the Pacific Ocean.

The dream of every numismatist is to get a coin that is worth a fortune or even how many fortunes. How do you like 10 million dollars?

The most expensive coins in the world

How much are the most expensive coins worth? How do they look? When were they released? Read on.

Flowing Hair Dollar translates as Dollar Loose Hair. It is the most expensive coin in the world and was last bought for $10,016,875. It was made of silver in 1794 - this is the first American silver dollar. The image of Liberty with flowing hair has been valued incredibly dearly throughout history. At the moment, about 200 of these coins remain in the world, although in 1794 2,000 of them were minted.

The Loose Hair Dollar was designed by Robert Scott, a well-known engraver. It was he who came up with the idea to mint a woman's head, symbolizing freedom, with her hair loose. On both sides of Freedom there are 15 six-pointed stars (8 on the left and 7 on the right) - that is how many states were part of the United States at the time of the issue of the coin.

The number of stars changed when the 16th state of Tennessee was added to the US. The rest of the coins were minted until the stamps were completely exhausted, after which the silver dollar began to be minted with 13 stars - that is how many of the original states were at the time of the founding of the United States.

The reverse of the most expensive coin in the world is decorated with a bald eagle surrounded by olive branches, which, in turn, are framed by the inscription UNITED STATES OF AMERICA. On the edge of the coin its denomination is indicated: HUNDRED CENTS ONE DOLLAR OR UNIT.

Saint-Gaudens Double Eagle- Gold coin "Double Eagle" Saint-Gaudens. This is a twenty dollar coin minted by the US Mint between 1907 and 1933. Double-Headed Eagles are considered the most beautiful and rare coins ever minted in the United States.

The coin is named after the designer who created it - Augustus Saint-Gaudens. He was the very first to respond to a call from the President (then it was still Theodora Roosevelt) regarding the decoration of American coins.

On the other side is an image of Miss Liberty, striving for the future with a torch in her hand. According to official figures, 12,367 of these coins were minted in 1907, while in 1933 their number increased by another 445,500. The rarity of the Double Eagles lies in the fact that they were never put into circulation due to changes, introduced into the currency legislation during the Great Depression - almost all the coins were seized and melted into gold bars, so each of the surviving copies today costs at least $ 10,000, but it is almost impossible to get them - the US security service responsible for preserving gold coins is vigilantly watching this reserves of the country within its borders.

The Sainte-Gaudens Double Eagle was last sold at Sotheby's for $7,590,020. Indeed, its place in the list of the most expensive coins in the world is fully justified.

Brasher Doubloon EB on Breast- Doubloon Brasher with the initials "EB" on the chest of an eagle. She was sold for $7,400,000. The coin contains 1 gram of pure gold.

It was created by American jeweler, silversmith Ephraim Brasher (EB). As early as 1787, this man submitted his petition to the New York authorities for the minting of copper coins, which was categorically rejected. However, Brasher was able to create various copper coins to complement the small amount of gold coins previously issued.

The coin, as numismatists admit, has an unprecedented historical significance; this precious rarity has become popular from the first days of circulation.

Florin of Edward III. This coin is also known as the Double Leopard, its face value is 6 shillings, but how much is one of the most expensive coins now? One of the three surviving 1343 florins sold at auction for $6,800,000.

Very rare medieval gold coin. She walked in Europe for ten months - from December 1343 to July 1344. The inscription on the coin seems very interesting - "MONETA RVPBLLE". In fact, it can be translated as - "ruble coin". As for the other side of the coin, it says: "REX EDOVARD (after this comes an incomprehensible badge)". Actually translated as - king (i.e. rex) Edward. As a result, what happens? The coin of the English king named Edward bore the name "RUBLE"!

Silver dollar I Class. This coin was minted in 1804 personally for the King of Siam, nicknamed the King of Coins for his passion for numismatics. Was sold for $4,140,000.

At the same time, an even more expensive coin was sold - the Silver Dollar I Class of 1804 from the Kweller collection. Interestingly, this coin was minted not in 1804, but in 1834, simply on the model of the earlier Silver Dollar. This is a very rare coin, which directly affects its value - in 2010 it was sold for $3,737,500.

This silver dollar has long been known as the "golden" king of American coins. The acquisition of the 1804th silver dollar is rumored among numismatists to grant immortality to the entire numismatic collection, so it is not only one of the most expensive coins in the world, but also very important.

Numismatic luminaries such as the King of Siam, Joseph J. Mikli, the Sultan of Muscat, Matthew Stickney, John Garrett, Louis Eliasberg, Colonel EHR Green, and Loreen G. Parmelee have something to do with the long and truly glorious “pedigree” of these coins. .

"Queen Elizabeth II". Numismatics fans know exactly how much one of the largest coins in the world costs, its weight is 100 kg. It was cast by the Royal Mint, located in Canada. On one side of this stunning coin, a portrait of the famous Elizabeth II is minted. As for the other side, here is just a maple leaf - a recognized symbol of the country.

The coin was sold for $4 million at an auction in Austria. Well, in principle, the amount does not seem so large due to the fact that the face value of the “royal coin” is 1 million dollars. In addition, it is worth saying that the fineness of gold here is the highest - 999. This is how the purest gold is designated.

Liberty Head Nickel. Liberty's Head Nickel Coin, denomination of only 5 cents, minted in 1913 without the knowledge of the US Mint in very limited quantities, which at the last auction is worth $3,737,500.

Collectors today agree that if a Liberty Head Nickel could be found in mint condition, it would be worth at least $20 million. In total there are several samples of this coin.

Olsen samples. Probably the most famous 1913 Nickels Liberty Head in existence, which was shown in print as well as on television.

Samples Walton. The famous J. O. Walton died in an accident on March 9, 1962. His 1913 Liberty Head Nickel was immediately declared a fake. Walton's heirs were left with coins created for George's order. Not so long ago, the coin was examined by numismatic experts. They admitted that the coin is indeed genuine. The American Numismatic Association Convention shortly thereafter helped reunite the Walton pattern with four others.

Norweb 1913 Liberty Head Nickel is now an exhibit of the National Numismatic Collection, located at the Smithsonian Institution.

Indian Head (Buffalo) Nickel. Introduced back in February 1913. This unit has become a kind of replacement for the Liberty Head design.

The most expensive coins of the Russian Empire

Konstantinovsky ruble. At an auction in the West, it was sold for $100,000. On one side of the silver coin, the state emblem of the Russian Empire is depicted - a double-headed eagle with a wreath of laurel leaves. Below it is the sign of the St. Petersburg Mint (S.P.B.). On the other side is a profile portrait with the date 1825. B.M. is written around the image. KONSTANTIN I IMP. and SAM. ALL-RUSSIA.

The edge of the ruble contains information about the fineness and weight of the coin in spools and fractions: ser. 83 1/3 samples 4 gold 82 14/25 shares. The Konstantinovsky ruble weighs 20.73 grams. Today, 8 types of this coin are known.

It is worth noting that Russian history does not know Emperor Constantine the First. But the ruble is not fake. If it turned out to be a numismatic curiosity, then the coin would not have been among the most protected during the reign of Nicholas I. Its existence became known only a couple of years after the death of Nicholas. Refuses, they minted a ruble with a portrait and the name of Constantine I during the dynastic crisis at the end of 1825. When the childless Emperor Alexander I died, Konstantin Pavlovich, his brother, was to ascend the throne. But only his mother and loved ones knew that he had abdicated. In 1823, the abdication appeared in the form of a manifesto of Alexander I, in which Nikolai Pavlovich was proclaimed heir. The manifesto was to be printed only after the death of Alexander I. But before it was opened, they began to swear allegiance to Konstantin. This formally made him the ruler of the country. At this time, the "ruler" himself was in Warsaw and sent a courier with confirmation of his renunciation. The interregnum lasted two weeks. And during this time, they just managed to mint coins with the image of Constantine I.

Kopek. It appeared in 1535 during the monetary reform of the mother of Ivan the Terrible, Elena Glinskaya. The reason for this was the introduction of the practice of cutting silver coins that were in use. This undermined the foundations of the monetary economy and caused people's mistrust. The weight of the money was about 0.2-0.3 grams, which is two times less than the original. Therefore, all old money was banned, and new ones were introduced into use.

At that time, Russian coins had an irregular shape, as they were minted on flattened pieces of silver wire. Because of the oblong shape, numismatists call a penny "scales".

The new coin depicts a rider with a spear. This is what it differed from the old money of Moscow, where there was a rider with a saber. Initially, the silver coin weighed 0.68 grams. Its weight was borrowed from Novgorod money, which is twice as heavy as Moscow money. As a result, one ruble was equal to one hundred Novgorod, 200 Moscow or 400 polushkas (a quarter of a penny).

Such a penny was issued until 1719. On its front side there was still the same horseman with a spear, and on the reverse side there was a line with a name and titles. The mint mark was under the horse. Over the years, and eventually became 0.38 grams. Gradually, the quality of silver also deteriorated.

In the 17th century there was an attempt to replace silver with copper, but it was unsuccessful. However, after another reform, the penny was replaced with a copper one. Only the 1925 coin remained in circulation among numismatists. About 50 remaining copies are not the most expensive coins of the USSR. The price of each is about 300 dollars.

Square penny. But the most expensive coin, not in terms of solvency, but in terms of actual price, is a square penny. Rare money has an unusual weight and shape. Only 10 such copies have come down to us - a square of 23 by 23 millimeters weighing 16.38 grams. It was produced in 1726 at the Yekaterinburg mint. At one of the Moscow auctions, this penny was sold for 2 million rubles. Although this is not the most expensive coin in the world, it occupies a worthy place as a historical value.

20 rubles. Even more expensive is 20 rubles in 1755. A gold coin with a face value of 20 rubles began to be issued after the monetary reform. Until that time, money of such dignity had never existed.

In 1755, only two such coins were minted. One copy is kept in the Hermitage, and the second was bought by a private collector at an auction in London. It cost him £1,550,000, not counting commissions. Thus, these 20 rubles broke the world record for the value that was paid for non-American money.

The most expensive coins of the USSR

Trial 1947 coins- the most expensive coins of the USSR. They never entered circulation, the entire circulation was melted down. Miraculously, only a few coins survived. No one really knows their value.

And here are the trial 1958 coins: 1 nickel ruble, 2, 3 and 5 rubles, as well as small change from one penny to fifty dollars, was disposed of in the same year. Therefore, the surviving ones cost a lot of money. For example, 5 rubles were sold for 184,500 rubles at an auction in Volmar.

change coins of 1927 coinage 2 kopecks, 3 kopecks and 5 kopecks can also be sold profitably. A kopeck piece at the auction is gaining more than 80 thousand rubles, a poorly preserved three-ruble note is 4 thousand rubles, and a good-quality nickel will cost $ 100.

Chervonets 1923- "Golden Sower" - goes for 80 thousand rubles. But the copper trial chervonets of 1925 was sold under the hammer in 2008 for 5 million rubles.

The most expensive modern Russian coins

Moscow Mint. Specialists give 120 thousand rubles for it. This money was not officially in circulation, but a few coins still went to the people.

More than twice the price can be sold 1 and 2 rubles 2001 issue of coinage of the Moscow Mint.

And here 5 kopecks 2002 and 2003 Petersburg Mint can be given for 3.5 thousand and 900 rubles, respectively. True, the coins were issued without identification marks.

Today the most expensive coins of Russia are commemorative coins of 25 thousand rubles. They weigh three kilograms and are made of pure gold. They were released on the 190th anniversary of Gosznak in 2008. In total, the bank received 50 copies. Interestingly, this “coin” could theoretically pay for a purchase in any store.

However, in 2010, a coin appeared even larger in terms of purchasing power. Gold money denomination 50 thousand Russian rubles weighs five kilograms and is also made of pure gold. 50 copies were issued, this time, for the 150th anniversary of the Bank of Russia. In theory, this coin can be accepted for payment as 50 thousand rubles. But its real value is much higher than face value.

Money is used all over the world and is available in various forms. In the past, coins were the most popular currency in the world. The coins were made from metals, many of which are rare and expensive, and also depicted various historical events important for the country and nation. Some people in the world love to collect coins as a hobby, and they are willing to spend a large amount to add rare coins to their collection.

Below are the 9 most expensive coins in the world.

10 US RED SEAL $1,000 1891

One of the oldest banknotes of the United States of America with a red seal from 1891. This banknote depicts the famous Major General George Gordon.

Next in the top will be the most expensive coins in the world.

9. Nickel coin Liberty Head 1913

The Statue of Liberty Nickel Head of America was made without permission from the US government and only 5 coins were minted before being banned from printing. One of the coins was issued in 1913 and later bought for almost $3.7 million, but some numismatists believe that this example can be sold for a higher price (presumably $20 million), this proves that a rare coin can be valued much more than precious.

8-7. Silver Dollar (Silver Dollar, Class I) 1804

6. Coin 1 million dollars 2007 (C $ 1M Coin)

This coin is very heavy and hardly suitable for frequent use, its weight is 100 kg.

Below is a summary table:

Top most expensive coins in the world

People who were still at the origins of market relations tried to come up with the most convenient way to pay for goods and services, but only with the advent of precious metals and the way they were processed and minted coins did the need to pay with stone circles or mirrors finally disappear. The era of coins has begun - metal money of various shapes and sizes, of which an innumerable number have been minted over the many centuries of our history, but hardly any of the contemporaries of the coins presented in this selection could believe how much they would cost, after only a couple of centuries. This article contains the most expensive coins in the world at the moment, according to the largest auctions in the world.

When it comes to the most expensive and historically significant specimens of ancient coins, the metal from which they are made no longer plays any role.

A rare silver or even copper coin can end up being much more expensive than a less rare gold coin.

So, the least expensive coin in the list of "The Most Expensive Coins in the World" was minted in the 19th century in Brazil in the amount of only 64 copies to commemorate the coronation of Pedro I, the founder of the Brazilian Empire and the favorite of its citizens. Pedro himself did not like being portrayed as if he were a Roman emperor, with a laurel wreath on his head. The coin was sold at a Chicago auction for $138,000.

A much more expensive coin is the gold dinar of Saudi Arabia, associated with the pilgrimage of Caliph Umar bin Abd al-Aziz. The rarest and oldest gold "Dinar Hashimi", which gave the name to a settlement in Saudi Arabia, was sold for $ 1 million at the British auction of Islamic coins "Baldwin". This dinar is considered the most significant coin ever minted in the Arabian Peninsula.

Brasher's gold doubloon with the initials "EB" on an eagle's wing, minted in 1787 and sold at a public auction for $2,415,000, turned out to be even more expensive. own coins, and coins to order. This man is also known for the fact that in the same year 1787 he sent a petition to the government of the state of New York with a proposition to mint copper coins as well, but his petition was rejected.

Half a million more expensive was the gold Double Eagle of Saint-Gaudens, sold at a recent auction for $2,990,000. This is a twenty-dollar coin minted by the US Mint between 1907 and 1933. Double-Headed Eagles are considered the most beautiful and rare coins ever minted in the United States. On the other side is an image of Miss Liberty, striving for the future with a torch in her hand. According to official figures, 12,367 of these coins were minted in 1907, while in 1933 their number increased by another 445,500. The rarity of the Double Eagles lies in the fact that they were never put into circulation due to changes, introduced into the currency legislation during the Great Depression - almost all the coins were seized and melted into gold bars, so each of the surviving copies today is worth at least $ 10,000, but it is almost impossible to get them - the US security service responsible for maintaining gold reserves is vigilantly watching this countries within its borders.

Absolutely the same final cost turned out to be, during an open auction in 1981, in another coin of the jeweler Ephraim Brasher already familiar to us - Brasher's Doubloon with the initials "EB" on the chest of an eagle was sold for $2,990,000 with a starting price of $625,000. This is one of few surviving Brasher coins. Her research showed that the total weight of the coin (26.6 grams) contains almost 1 gram (0.917 grams) of pure gold.

Even more expensive was the nickel coin Head of Liberty (meaning the Statue of Liberty) - an extremely rare coin worth only 5 cents, minted in 1913 without the knowledge of the US Mint in very limited quantities. The first copy put up for auction in 1972 "went under the hammer" for $ 100,000, then, in 1996, another 5 cents raised the bar to the million barrier. At the same time, it was stated that if the Liberty Head was found in perfect condition, its value could exceed $20 million. Until now, no one has found such a coin, or at least no one admits to it. The next 5 cents were sold in 2003 for $3 million, and finally, in 2010, at an open auction, the next sample reached $3,700,000, becoming the most expensive 5-cent coin in the world. To date, only five existing nickel coins of the Head of Liberty are known - two of them are in museums, the remaining three are in private collections.

At the same time, an even more expensive coin was sold - the Silver Dollar I Class of 1804 from the Kweller collection. Interestingly, this coin was minted not in 1804, but in 1834, simply on the model of the earlier Silver Dollar. This is a very rare coin, which directly affects its value - in 2010 it was sold for $3,737,500.

The next coin is fundamentally different from those presented above. We are talking, in fact, about a huge round piece of gold called Queen Elizabeth II, which is now the largest gold coin in the world. It weighs exactly 100 kilograms, 99.999% of which is gold, making it the purest example on the world coin market. Queen Elizabeth II was minted at the Royal Canadian Mint. On one side of the coin, the symbol of Canada - a maple leaf - flaunts, on the other - the profile of Queen Elizabeth II. The sale of this coin at the Dorotheum auction of the Austrian auction house of the same name brought the owner $ 4 million - despite the fact that he bought it for "only" $ 1 million.

The small Silver Dollar of 1804, however, turned out to be worth more than a huge piece of gold. Just like the Class I Silver Dollar, this coin was minted in 1834 and has a unique history. During the minting of silver dollars, the coins were divided into "classes", with only 15 of these coins in existence, eight of which are Class I (minted in 1834), one Class II and six Class III (minted between 1858 and 1860). ). In addition, a Jubilee coin was issued personally for the King of Siam, which became a worthy representative of the vast collection of this monarch, nicknamed even, for his passion for numismatics, the "King of Coins". The fourth most expensive coin in the world was bought in 2001 by a private collector who purchased the entire King of Siam coin set for $4.14 million.

Rounding out the top three is the rare Edward III, a golden medieval double florin that was in circulation from 1343 to 1344. This coin is also known as the Double Leopard and has a face value of 6 shillings. Auctioned by Spink for $6.8 million, Edward III is one of three surviving and now known double florins from 1343.

In second place on the list of "The most expensive coins in the world" is the already familiar (but this time gold) Double-Headed Eagle of Saint-Gaudens minted in 1933. According to Mark Pakter of the National Museum of American History, this coin is a symbol of the common struggle against an interdependent global economy, both at the beginning of the 20th century and today. The coin was sold at auction for $7.59 million.

The most expensive coin in the world at the moment is the so-called Loose Hair Dollar. This rare coin, minted in 1794 in silver, was sold from the IRVINE Rare Coin Collection for $7,850,000. Throughout the history of the dollar, the 1794 Loose Hair has always been considered one of the rarest and most valuable coins of the United States of America. For its sale, an official deal was made between the president of the Rare Coin Wholesalers of Irvine association, Stephen Contursi, and the Cardinal Collection Education Foundation.

As you can see, there are 12 coins in the "Most Expensive Coins in the World" rating, but we do not take into account the repeated doubloons of Brasher and the Double-Headed Eagle - if we take into account only the most expensive of them, then your attention is presented to the ten most expensive coins in the world.
