Executive Order 6102 required all persons to deliver on or before May 1, 1933, all but a small amount of gold coin, gold bullion, and gold certificates owned by them to the Federal Reserve, in exchange for $20.67 (equivalent to $372.75 today[3]) per troy ounce.

The United States Gold Reserve Act of January 30, 1934 required that all gold and gold certificates held by the Federal Reserve be surrendered and vested in the sole title of the United States Department of the Treasury.[1][2]

The Gold Reserve Act outlawed most private possession of gold, forcing individuals to sell it to the Treasury, after which it was stored in United States Bullion Depository at Fort Knox and other locations. The act also changed the nominal price of gold from $20.67 per troy ounce to $35.
