<p>[QUOTE=&quot;-jeffB, post: 2678118, member: 27832&quot;]Yep, the environment can&#039;t attack zinc if it can&#039;t get to it.</p><p><br /></p><p>I <i>suspect</i> that many Zincolns have very weak spots in the plating as a result of the normal striking process -- that plating is going to be stretched and thinned where there&#039;s strong relief on the coin. If this exposes any microscopic voids, cracks, or pinholes that go all the way through, that&#039;s enough for the process to start, even if the coin never sustains a <i>visible</i> post-strike hit.[/QUOTE]</p><p><br /></p>
