Wife dumped her Mom's old piggy bank on the table and I went through and sorted out anything interesting to me. Have a quart size bag of general circulation wheat pennies that are filthy and actually stink from where they were stored.
Question: Would it hurt anything to dump them in vinegar and clean them up to actually see what the coins look like and read the date?
