Authorized by Congress in 1996 and first issued in 1997, they are the first and only official investment-grade platinum coins from the United States Government.
American Eagle Platinum coins are part of a complete precious metals portfolio available from the United States Mint. The American Eagle Platinum is the only platinum bullion coin whose weight, content and .9995 purity are guaranteed by the United States Government.

All American Eagles are legal tender coins, with their face value imprinted in U.S. dollars. Although their face value is largely symbolic, it provides proof of their authenticity as official U.S. coinage. The one-ounce platinum coin displays the highest face value ($100) ever to appear on a U.S. coin.

Each coin was manufactured at the Pobjoy Mint in England from 1983-1989 and is composed of 1 troy ounce of .9995 pure platinum. Isle of Man coins were legal tender under protection of Great Britain, but had no face value. Their assessment was based completely on bullion content.
Platinum Noble pieces — often named "Manx" — were the first platinum bullion coins created primarily for investors in 1983.
The Isle of Man 1 oz Platinum Nobles are no longer produced and have a limited availability.

The Platinum Koala is an Australian platinum bullion coin minted by the Perth Mint and is the most famous series of platinum coins of Australia. The Platinum Koala is notionally legal tender, that is a legal means of payment (in Australia).
On 18 June 1987, the Australian Government approved the minting of platinum and silver coins.
Together with the American Platinum Eagle, the Platinum Koala is one of the very few series of platinum coins which are still being produced.
