Thanks guys. I don’t know if they are polished a friend had a few in a box in his desk for the last 20 years or so, and gave them to me. Thanks again for the input.
I cannot decide whether it was polished or even plated with another metal.
In any event, if you pay the fees to send it to be slabbed, they will keep your fees and return the coin in a "body bag" (a plastic bag, with a statement as why not graded or slabbed)--definitely a waste of money.
