You stated &quot;die deterioration&quot; and asked a question.</p><p>I think the &quot;bubble&quot; that you refer to is just from the pressure of the die on copper coated zink planchet. It is more difficult to mint the newer/post 1981 penny. In fact, there was a switch to &quot;small date&quot; in 1982, when zinc was introduced, because there was difficulty during the transition. The small date was easier to mint.[/QUOTE]</p><p><br /></p>
