What would the size of the coins be? Given the inflation over the years, we would have to re scale all the coins to match the metal. Currently, from my best guess, the amount of silver content in the pre 1967 dime is worth more than $3 now. And the amount of silver in the old silver dollars is now worth about $36. Given the bubble in gold right now I don't even want to speculate on the value of the lowest gold coin that would circulate. If we would go back to a metal system, what denominations do you think the coins would be?
