<p>[QUOTE=&quot;Hookman, post: 3296166, member: 99642&quot;]From what I&#039;ve gathered from other, more knowledgeable members, that looks like </p><p>&quot;zinc rot&quot;. Modern pennies are a thin coating of copper over a zinc core. Zinc rot occurs when during the original striking of the coin, a small, even minute, fracture of the copper plating occurs and allows moisture/water to come in contact with the zinc core. Zinc is reactive to water. Over time, the zinc and moisture combination begins to &quot;rot&quot; and eventually you have what you see here. This interaction is more common around the mint mark.[/QUOTE]</p><p><br /></p>
