<p>[QUOTE=&quot;jloring, post: 1240809, member: 15518&quot;]It&#039;s not the machining process... that will always leave tool marks. It&#039;s the post machining (polishing) process that eliminates all signs of the actual machining. Why would someone take the time to do this? I haven&#039;t a clue. Maybe I can get one of my co-workers out in the shop to put a cent in the surface grinder and then buff out the marks. See if it can be done as simply as it sounds. </p><p><br /></p><p>If this &#039;error&#039; happened during the minting process, I would need an explanation as to how.[/QUOTE]</p><p><br /></p>
