Is it safe to use electrolysis on a "Shield" nickel? I found one a while back, and it is in very poor shape-I can barely discern anything on it except for the "5", and a few bars on the back. I know in general it's best for silver coins, gold, dimes and quarters, but what about nickels? I know it is not good for copper pennies. I haven't used electrolysis yet on anything but am considering it, especially for saltwater coins (Mercs).
Thanks,
Todd
