<p>[QUOTE="desertgem, post: 6443258, member: 15199"]Acid removes the copper alloy at same rate in all directions, so the coin is less size in height and obverse and reverse. If same size physically, check for a very small cut around the inside surface of the rim where someone used a lathe to remove the internal mass. Often called a magician coin if one side is correct and the other is a different value coin. Jim[/QUOTE]</p><p><br /></p>
