<p>[QUOTE=&quot;desertgem, post: 905830, member: 15199&quot;]With the newer services of NGC and PCGS, you can have a very scientific report on the composition of your nickel, once you have determined there is a good chance of that being the case. Since the nickel blanks are alloyed (solid) , and the size is correct, it is difficult to imagine how copper cent strips could have been punched by the nickel punch to produce the correct size and then fed into the striking press. I guess it could be mischief by the coiners, but I would guess it is more likely a chemical alteration of the surface. </p><p><br /></p><p>The weight would not generally give a definitive answer as the specific gravity of copper and nickel are almost identical at 8.90 +/-&nbsp; small % .</p><p><br /></p><p>Jim[/QUOTE]</p><p><br /></p>
