Well, I’m shocked.
Back in those days, people had few options on what to do with it. Ma and Pa Kettle couldn’t get their gold to Vietnam, if they had ever HEARD of Vietnam. Immediately after the turn in order, that 20 dollar gold piece was worth 35 bucks as Roosevelt revalued the dollar.
Today that would be impossible. Thousands of airline flights per day leave the USA. You can probably order a CONEX box full of Chinese 12 year olds to work in your restaurant kitchen. A small bag of coins is childsplay. The rest of the world would laugh at a turn in order. And your gold will be readily convertible as long as there is an Indian, Vietnamese, Chinaman in your city.
That was a one-trick pony from the 1930s.
