In 1986, the American Eagle was first minted in pure gold and sterling silver. The American Eagle is named after a gold coin that was minted in the United States from 1795 until the ban on private gold in 1933 under the name Eagle. In the original version, the motifs of the portrait of the walking goddess Svoboda on the face and the bald eagle on the reverse are still preserved. The reverse of the coin shows the weight and fineness (bottom left), the face value (bottom right) and the name of the country. The "American Eagle" gold coin has been minted by the US Mint since 1986 in four weights, 1oz, 1 / 2oz, 1 / 4oz and 1 / 10oz. The silver coin is minted in only 1 troy ounce. Production of platinum "American Eagle" in weights of 1oz, 1oz, 1oz and 1 / 10oz begins in 1997. 11/12 of the weight of a gold coin (corresponding to the purity of 916.67 / 1000 or 22 carats) consists of pure gold weighing 1 troy ounce. The remaining 1/12 contains alloys of copper and silver. This alloy gives the coin (5.33% copper, 3% silver) greater hardness and scratch resistance and gives the coin a red tinge.
