Google/Bing Executive Order 6814. FDR went after holders of 50,000 0z of silver or holders of 2 or more futures contracts. Called them silver hoarders.
Correction, people with over 500 ounces of silver. The initial proposal was for 50,000 and over.
Well, since there is no record of the purchase of a single oz oz of silver I own, I guess I’m not a hoarder. :)
