United States Mint — gold and silver coins from the USA
Number of products: 24The United States Mint — history since 1792
The United States Mint was created by the Coinage Act of 2 April 1792, and its first works opened in Philadelphia — then the capital of the USA. Today the mint runs branches in Philadelphia, Denver, San Francisco and West Point, and also has custody of the gold depository at Fort Knox. Bullion coins, including the American Eagle, are produced mainly at the West Point mint in New York State.
Over more than two centuries the mint has struck some of the most recognisable coins in history — from the circulating 19th-century Liberty gold eagles, through the Double Eagle designed by Augustus Saint-Gaudens (1907), to modern bullion series. That design heritage is still present in the mint's products: the obverse of the gold American Eagle uses the Saint-Gaudens composition of more than a hundred years ago.
United States Mint bullion series
| Series | Metal and fineness | Since | Distinctive feature |
|---|---|---|---|
| American Gold Eagle | gold 916.7 (Au/Ag/Cu alloy) | 1986 | obverse after Saint-Gaudens; Type 2 reverse since 2021 (Jennie Norris) |
| American Silver Eagle | silver 999 | 1986 | the best selling silver bullion coin in the world |
| American Buffalo | gold 999.9 | 2006 | the first American bullion coin at 24-carat fineness |
Each of these coins carries a denomination in US dollars and legal tender status.
916.7 fineness in the gold Eagle — why not 999.9
The American Gold Eagle is struck in an alloy of 916.7 (22 carat): 91.67% gold, 3% silver and 5.33% copper. The additions do not reduce the metal content — the 1 oz version holds exactly 31.1035 g of pure gold, with a total mass of 33.93 g. The alloy makes the coin distinctly harder and more scratch resistant than coins at 999.9 fineness. For buyers who prefer pure gold, the mint introduced the American Buffalo series at 999.9 fineness in 2006.
