'Presidential Executive Order 6102, April 5, 1933, made it illegal to "hoard" gold. The order exempted anyone whose "usual and customary" business required gold. (Dentists and jewelers come to mind. Electronic fabricators would come under this once electronics was invented.) Anyone could own up to $100 in gold coin. In 1933, $100 was two or three months wages for the average worker, about $6000 to $10,000 in today's money.'
