<p>[QUOTE=&quot;SuperDave, post: 2752529, member: 1892&quot;]It&#039;s &quot;solid&quot; in the sense of being one continuous alloy, yes. Now, let&#039;s consider how much of that alloy was needed <i>just to produce 1942-dated Cents</i>. According to my calculations, that number approached <b>3300 tons of alloy</b>. Or, something over <b>150 full modern tractor-trailer loads at maximum gross weight</b>.</p><p><br /></p><p>That&#039;s a lot of metal to produce with perfect homogeneity, and I don&#039;t think they always succeed. One can assume that there are places of improper mixing (&quot;Woodie&quot; Lincolns hint at this), bubbles trapped in the final product, rushed cooling leading to brittle areas, things like that. All sorts of potential imperfections which could lead to delamination down the road; indeed, the Mint preparation process could be a factor.</p><p><br /></p><p>Ain&#039;t hard to understand once you envision the scale of things. <img src="styles/default/xenforo/clear.png" class="mceSmilieSprite mceSmilie1" alt=":)" unselectable="on" unselectable="on" />[/QUOTE]</p><p><br /></p>
