<p>[QUOTE=&quot;Conder101, post: 1548676, member: 66&quot;]It doesn&#039;t happen when the planchets are struck, it occurs when they are punched from the strip.&nbsp; </p><p><br /></p><p>The copper nickel layers on the strip are of equal thickness.&nbsp; Now when the punch comes down the metal is sheared at the edge of the planchet.&nbsp; As the planchet is driven down the metal on the edge of the planchet is smeared upward with the bottom layer of coppernickel and copper pretty well covering the edge of the top layer of coppernickel.&nbsp; If you look at the edge you see two layers of metal and possibly only a trace of the second coppernickel layer.&nbsp; If you look at the edge of the hole in the strip you will see that on it the metal has been smeared downward with the upper coppernickel and copper layers visible and only a trace of the bottom layer.&nbsp; (Ihis is important when examining &quot;clipped planchet&quot; clad coins.&nbsp; On a genuine clip the metal will be smeared in one direction on the edge of the planchet, but in the other direction inside the clip.)</p><p><br /></p><p>Since the planchets get jostled around there is no way to control how they enter the coining chamber, so roughly half of them will smeared toward the obverse and half toward the reverse.[/QUOTE]</p><p><br /></p>
