<p>[QUOTE=&quot;desertgem, post: 3020168, member: 15199&quot;]The outside layers of the coin is&nbsp; 25% nickel and 75% copper which have a nickel color, whereas the center is 100% copper. In your photo of the side, at the edge farthest to left side of photo, I can see the 3 layers. If the layer closest to the part worn down doesn&#039;t show both of the outer layers, it is because someone reduced the edge by sanding or grinding it down with a very fine abrasive, so it is PMD whether intentional or not by&nbsp; previous owner.
