<p>[QUOTE=&quot;desertgem, post: 3695881, member: 15199&quot;]Your s mm is a good example of something many people would quickly and wrongly think is a rpm rather an already mentioned die chip. The only visible difference from it and a clean rpm is the material at the top opening of the S and the 2 smallest angles in the bottom loop. This cause by a damaged MM punch as the protruding part to make the gap are the thinnest area of metal and after repeated us , the tips for those areas are broken off so nothing to prevent the metal from rising in that area when the punched die is used to make coins. Most new think immediately it is a RPM, like Paddyman said above about the culprits. Jim[/QUOTE]</p><p><br /></p>
