My grandfather passed away in Dec. and I have
inherited boxes of coins. Unfortunately I started researching the sets first and didn't realize there was a purpose to all the loose change until we had deposited it in the bank. Anyway while sorting loose pennies (thousands) I encountered this dime, I am new to coin collecting and its been a trial by fire with missteps along the way as I mentioned previously.
Is this coin valuable?
Should I clean it and how?
Any help would be appreciated.
