“On April 5, 1933, one month after taking office, Roosevelt used the powers granted to the president by the Trading with the Enemy Act of 1917 to make gold ownership illegal. He issued Executive Order 6102, which made gold ownership—both in coins and in bars—illegal for all Americans and punishable by up to ten years in prison. Anyone caught with gold would also have to pay a fine of twice the amount of gold that was not turned over to the Federal Reserve in exchange for paper money.”
