The United States $20 Gold Double Eagle was produced for from 1850 to 1933 when all gold coins were pulled from circulation. Only collectors could keep their gold coins except for the 1933 double eagle. That is because a few were minted, but not legally. There is a fascinating story of a private collector that claimed she inherited ten of these 1933 double eagles. She was told by the Mint that these coins were stolen and was forced to give them up. Lawsuits began and the mint was given ownership. The decision was reversed, and then reversed again. There are more stories of 1933 double eagles that you should look up including the one owned by King Farouk of Egypt. Who said coin collecting was dull?
