Congress additionally passed the Gold Reserve Act in 1934, which outlawed the circulation and private possession of United States gold coins for general circulation, with an exemption for collector coins. This act declared that gold coins were no longer legal tender in the United States, and people had to turn in their gold coins for other forms of currency. The 1933 gold double eagles were struck after this executive order, but because they were no longer legal tender, most of the 1933 gold coins were melted down in late 1934 and some were destroyed in tests. Two of the $20 double eagles were presented by the United States Mint to the U.S. National Numismatic Collection, and they were recently on display in the "Money and Medals Hall" on the third floor of the National Museum of American History.
