<p>[QUOTE=&quot;Conder101, post: 1212326, member: 66&quot;]No plating bubbles and a lamination error are not the same thing.&nbsp; A plating bubble is caused by gas that gets trapped between the core and the plating when it is applied.&nbsp; A lamination is caused by gas bubbles or foreign matter trapped inside the metal ingot when it is poured.&nbsp; When the ingot is rolled out the bubbles are &quot;stretched out&quot; creating voids and layering inside the strip.&nbsp; If these voids break through to the surface you get a lamination error and in some case the layers of metal will actually flake away.&nbsp; If they break through at the side of the coin you can have a clamshell split planchet, or part of the coin may break away.&nbsp; In some case the coin may split completely in two.[/QUOTE]</p><p><br /></p>
