Found this coin today: Any idea on value? I did a test by scatching it a bit, doesn't appear to be plated with zinc or mercury. Thanks, Tim
Welcome to the forum Tim. That's because it is solid zinc, from which the copper plating has been removed - probably chemically.
Could be struck on an unplatedplanchet, in which case it would be worth a few $$. But......DO NOT EVER "TEST" SOMETHING BY DAMAGING IT. Whatever value it had has been seriously hurt by your testing.
