The English florin, sometimes known as the double leopard, was an attempt in 1344 by Edward III to produce gold coinage suitable for use in Europe as well as in England. It was authorised on 27 January 1344, and struck from 108 grains of nominal pure ('fine') gold and had a value of six shillings.
The five pound British gold coin, also known as a quintuple sovereign, has a nominal value of five pounds sterling. It has been struck intermittently since 1820, though as a circulation coin only in 1887, 1893 and 1902. Through most of its history, it has depicted, on its reverse, Benedetto Pistrucci's portrayal of St George and the Dragon, which has traditionally been used on the sovereign, or one-pound gold coin.
Coin grading is the process of determining the grade or condition of a coin, one of the key factors in determining its collectible value. A coin's grade is generally determined by six criteria: strike, preservation, luster, color, attractiveness, and occasionally the country/state in which it was minted. Several grading systems have been developed. Certification services professionally grade coins for tiered fees.
The 1933 double eagle is a United States 20-dollar gold coin. Although 445,500 specimens of this Saint-Gaudens double eagle were minted in 1933 in the midst of the Great Depression, none were ever officially circulated, and all but two were ordered to be melted down. However, 20 more are known to have been rescued from melting by being stolen and found their way into the hands of collectors before later being recovered. Nine of the recovered coins were destroyed, making this one of the world's rarest coins, with only 13 known specimens remaining—only one of which is privately owned, which is known as the Weitzman Specimen. Because the coin was never released to the public, it is illegal to privately own any of the 1933 double eagles, with the exception of the Weitzman Specimen. The United States Secret Service is said to investigate reports of the existence of other specimens that come to light.
