The American Gold Eagle is a gold bullion coin authorized for production by the Gold Bullion Coin Act of 1985. First production runs started in 1986 from several US Mints. They are minted in four sizes - tenth of an ounce with a face value of $5, quarter of an ounce with a face value of $10, half an ounce with a face value of $25, and a full ounce with a face value of $50.
