I'm not sure about this coin.. It is a dark color, almost black. It has not been burnt or anything, it's the color of the metal. The penny weighs 2.45 I am thinking it might be struck on a dime planchet. I took a pic of it beside a 95 Lincoln cent to show the difference in the color. What do you think?
Yes to Environmental Damage. If it were struck on a Dime Planchet it would be Clad over copper core and smaller in diameter.
