Florin of the time of Edward III
In the Middle Ages, the florin gold coin circulated throughout Britain. Apparently, she did not have a herd (rib), and on one of the sides, King Edward III is depicted on the throne. At that time, the quality of minting had not yet reached perfection, so some elements are difficult to identify. Florins were made of pure gold, the denomination corresponded to 6 shillings.
Florin was issued in 1343, belongs to the first edition of the minting of English coins. Already in 1344, these coins were withdrawn from circulation, because their weight did not correspond to the face value. The circulation was melted down. Three coins have survived, two of which are in the British Museum, and one sold at auction in 2006 for $ 6.8 million.
Brasher's Golden Doubloon
This copy was minted by the American jeweler Ephraim Brasher in 1787. He created coins to order, and sometimes for himself. It is unknown how many such doubloons exist, but no more than 7–10.
The name is due to the fact that the coin weighed the same as the Spanish doubloons, which were circulated in all states of America - 26.6 g.
In fact, there is only 1 gram of gold in the coin. It is distinguished by the presence of the master's initials, the quality of the minting and a very small number of copies. In 2011, Brasher's doubloon was purchased at auction for $ 7.4 million by the Wall Street Foundation for an anonymous collector.
$ 20 "Double Eagle"
"Double Eagle" is a gold rush coin. It was minted from 1849 to 1933. With the onset of the Great Depression, the US government was forced to abandon gold coins, they were taken out of circulation and melted down. However, several (about 10) pieces were stolen and bought by the jeweler Israel Sweet. But the secret services found the coins and confiscated all but one sold to the king of Egypt. Then she got to the British Stephen Fenton, who, at the request of the US authorities, was forced to put it up for sale. The coin was purchased in 2002 for $ 7.5 million, and the proceeds were shared by Stephen Fenton and the US Treasury.
In 2004, 10 more coins of the 1933 minting were found and taken away from the heirs of Israel Sweet. They were not smelted, but sent to Fort Knox, a gold bullion storage facility in the United States.
1972 Dollar "Loose Hair"
The Loose Hair Silver Coin is one of the most expensive to date. This dollar was issued for only two years - in 1794 and 1795. The circulation during this period was 162,000 copies. Only 2,000 were put into circulation, and 200 coins were immediately melted into silver due to the poor quality of the minting. The rest were given away.
Now there are about 200 coins on the planet. There is accurate information that one of them was sold for $ 7.85 million by Stephen Contursi, President of the IRVIN Association, from the official collection of the same name.
Each of these 10 coins is unique in its own way. That is why numismatists strive to get them in their collections.
