I have a penny that is blank on one side and some kind of clear coat on the other side. What is it and what is it worth?
Welcome to CT! It would be interesting to know what it weighs. Chances are, the coin was altered for some other purpose. Meaning, no added value.
It looks as if it was a display, it has a little glue on the blank side. And the clear coat is raised.
It should weigh 3.11 grams (bronze-pre1983) or 2.5 grams (copper-plated zinc-post1982). It's definitely altered/damaged.
The Magic Man is correct. Probably part of a Tails-Tails coin. A novelty and if intact, would have had some value. As is...nothing.
