<p>[QUOTE=&quot;cpm9ball, post: 2153614, member: 24633&quot;]Yes! This happens when grease and debris build up in the incuse devices. As more and more coins are struck, it becomes compacted until such time that the device is completely filled, and the incuse element of the design disappears.</p><p><br /></p><p>Although a grease-filled die is very common and can be found on almost every denomination of our coinage, what you really want to be on the lookout for is the &quot;dropped element&quot;. The grease and debris that is compacted in an incuse device can become almost as hard as steel. Sometimes, it will fall away and land on the incoming planchet before it is struck. When this happens, the design element is then pressed into the coin. It may remain embedded in the coin, or it may just fall away once the coin is ejected from the coining chamber. A &quot;dropped element&quot; is rarer than a grease-filled die, and a &quot;retained dropped element&quot; is even rarer.</p><p><br /></p><p>Chris[/QUOTE]</p><p><br /></p>
