<p>[QUOTE=&quot;rzage, post: 2164142, member: 14070&quot;]Aren&#039;t die scratches the result of polishing the finished die . If so they would be on the coins as the dies were already hubbed . Also I was wondering , when you hub a die , isn&#039;t the die still relatively soft and the positive hub hardened . Being an retired tool and die maker . When you face a piece of metal , with high speed , ie rpms . And slow feed (travel) the lines are very negligible but if you&#039;re in a hurry to remove metal large grooves remain . Still I&#039;ve seen someone take a ballpeen hammer to the face of a piece and all traces of the lathe lines are removed . Now you&#039;ve probably forgotten more than I ever could know about the hubbing process and die preparing . My question is how often are the lathe lines seen on the devices and if they aren&#039;t removed in the hubbing process most of the times as Doug said ?[/QUOTE]</p><p><br /></p>
