Platinum coin
The American Platinum Eagle is the official platinum bullion coin of the United States. These coins are made of 0.9995 pure platinum with face values of 10, 25, 50 and 100 dollars and were first released by the United States Mint in 1997. The design of coins of different values is almost the same, except for some numerical values. The 2009 minting of Platinum Eagles was uncertain due to rising metal prices; however, the issue of 8,000 one-ounce coins was announced in October. The price was set at $1,792, and the entire edition was sold out within a week.
