When did the u. s. dollar become part of a total fiat system?

Hey there,

Your question states: When did the U.S. dollar become part of a total fiat system?

I would say that your correct answer would be "when modern dollar printing originated" because the government would have to declare the money first and then it would be known then after it would be sent. So this would conclude that the U.S dollar became part of a total fiat system soon after is was announced.

Hope this helps.
