The American Eagle coin program came about after private Gold ownership was reinstituted in the United States. Prior to this point, from the time of President Franklin Roosevelt’s Executive Order 6192 in 1933, private Gold ownership had been banned.
The Platinum Eagle was first struck in 1997, but it took a couple of years of work to get it to that point. Platinum Eagles have been made in 1/10, 1/4, ½ and 1 0z weights, with $10, $25, $50 and $100 denominations.
President Gerald Ford lifted the restrictions of Executive Order 6192 on December 31, 1974, and soon after that point, the U.S. Mint began exploring programs to offer Treasury-owned Precious Metals to the public.
