In 1986, the United States began striking silver and gold bullion coins to compete with world bullion coins such as the Canadian Maple Leaf, the South African Krugerrand, and others. The value of these coins is tied directly to their metal value. The obverse of U.S. gold bullion coins follows the artistic design created by Augustus Saint-Gaudens for the $20 Gold Double Eagles issued from 1907-1933. The design features Lady Liberty carrying an olive branch and a torch. The American Gold Eagle coin is priced based on the spot price of gold plus a mintage premium.
