Thank you for your insights. I’m aware of the dollar definition (1/20th of an ounce of gold). Did you know that while the silver certificate was redeemable for silver (coin silver is 90% silver), an FRN is not redeemable for anything other than to pay debts. 1933 saw the devaluation of the dollar via a change in the price of gold.  But my question was what happens when we leave this Federal Reserve economy?
