<p>[QUOTE=&quot;Conder101, post: 5169706, member: 66&quot;]When the strip is rolled out the upper and lower coppernickel layers are pretty much the same thickness.&nbsp; When the blank is punched out of the strip a &quot;smearing&quot; of the layers occurs.&nbsp; If you were to look at the edge of the hole left in the strip you would see the top CuNi layer has been smeared downward and well appear thick.&nbsp; The copper layer will also smear downward and appear thick.&nbsp; The bottom CuNi layer has nowhere to go and is partially covered by the copper layer.&nbsp; It may or may not be visible at all but if it is it will be thinner than the top layer.</p><p><br /></p><p>On the edge of the blank this same smearing occurs as well but in the opposite direction. In this case the layers smear upward and the top CuNi layer is the thin one. (This is one test for authenticating a clipped planchet on a clad coin.&nbsp; On a genuine one the smearing on the edge of the coin and in the clipped area will be in opposite directions.&nbsp; Not foolproof but a good indication.)[/QUOTE]</p><p><br /></p>
