<p>[QUOTE=&quot;BR549, post: 1234489, member: 7110&quot;]Now days, three different vendors supply the cent planchets to the US Mints. These cent planchets must be within the allowable variances set by the mint. Since the end of 1982, the zinc cores&nbsp; are stamped out by a blanking press, then the blanks are feed through an upset mill. This produces the curved edge on the zinc core, which is now called a Type II planchet. The curved edge helps increase die life and improves the affect of the dies striking the planchets. Also, the curved edge assist the metal flow into the dies. After going through the Upset Mill, the outer plating of copper is applied to the zinc core and becomes a planchet. The completed cent planchets are now ready to be shipped to the mint for production runs.</p><p><br /></p><p>The 2.5% copper jacket by weight is thicker near the rims to allow for wear and thousands of an inch thick in the design area. I have seen struck cents where the copper jacket is completly missing, but the design elements are fully struck into the upset zinc core. </p><p><br /></p><p>If two coins enter the striking chamber together, the bottom coin will receive the tails design while the top coin receives the heads side, with nothing in between the two coins. But what happens during the striking process every time, is the metal flows and deforms around the edges, squished together like two jelly donuts. </p><p><br /></p><p>The cent depicted does not have this deformation so we can conclude that two coins were not together while being struck. l&#039;m also not saying that only one side was plated during the mfg of this coin, but is improbable because you have a complete heads with the copper jacket intact with a blank reverse missing the copper jacket and the upset from the mill....case closed, post mint damage.
