<p>[QUOTE=&quot;John Burgess, post: 3627555, member: 105098&quot;]Zincolns aren&#039;t annealed, the Zinc is already soft enough to roll out punched and plated afterwards so thinly, it still remains soft enough to strike that annealing isn&#039;t necessary. Copper plated Zinc Cents are composed of Zinc Alloy 190 electroplated with 8 microns of copper. The zinc used (Zinc Alloy 190) is identified as being &quot;self annealing characteristics&quot;, soft enough to not need to be annealed to work with it.</p><p>&nbsp;</p><p>Lamination errors are, I think, impossible on Zincolns because it&#039;s a plated coin, if anything you&#039;d get plating blisters under the plating, but not a delamination type fracture or splitting from impurites in an alloy.[/QUOTE]</p><p><br /></p>
