The History of the US Dollar

I want a definition. It would be legal as long as there's no fraud involved. But you still have to have a definition. I can define a gold dollar. And for us it was not rounded off. At the time of the Constitution,. they had a precise weight of silver, which was the real monetary issue. When we lost to war in Vietnam, we left and all of a sudden something weird happened. They started acting like capitalists. We were only an hour, a year or so on World War I and World War II. Think of how that was taken care of. The world has never been on a fiat currency to the extent that we're now with the paper money dollar
