I have a Silver Penny. During World War II, there was a great need for copper for the war effort. In 1943, Zinc was substituted for the copper. I have a Buffalo Nickel. Buffalo Nickels must show a full date and have a value of thirty cents each and up.
Buffalo nickels with excessive wear showing no dates are worth about ten cents.
I have a Silver Dollar. I have a Silver Certificate. I have Silver Coins. 100's of millions of these coins were minted. Present value is based on a calculation of the price of spot silver on the commodity markets.
