<p>[QUOTE="The_Cave_Troll, post: 67126, member: 1674"]1976--Please don't yell at us (type in all caps) it is rather rude. As for your coin, copper can tarnish (tone) to look like brass, but my guess is that the chemical composition of the metal was just off a little. Brass is ~75% Copper and ~25% Zinc while the propper composition of a 1976 cent is 95% copper and 5% zinc. It is not unheard of for the metals to not be perfectly alloyed and my guess is that is what happened to your coin. If that is the case I'd imagine that it has very little additional collector value.[/QUOTE]</p><p><br /></p>
