Since its introduction, the Platinum Eagle has become one of the world's most widely-traded Platinum bullion coins. Released in 1997, the Platinum American Eagle is the only investment-grade Platinum coin from the U.S. Mint. It is the only bullion coin the U.S. government guarantees for weight, content, and .9995 purity. The 1 oz Platinum American Eagle has a $100 face value - the highest of any American coin ever minted.
Burnished Platinum Eagles are created through a specialized minting process. Burnished coin blanks are hand fed into specially prepared presses one at a time. Although the appearance of the coins is similar to the bullion versions, these uncirculated versions typically have a superior strike and finish and are handled more delicately. These coins were referred to as collectible uncirculated versions and feature the "W" mint mark for West Point.
