<p>[QUOTE=&quot;mikediamond, post: 830461, member: 1859&quot;]Very well, then.&nbsp; Since you&#039;ve stopped shouting and cussing, I am quite willing to apologize for an unusually blunt reply.&nbsp; Here&#039;s the deal.&nbsp; The doubling is incuse, and strongly so. So you can&#039;t argue that away.&nbsp; There is no die polishing and it is never an ingredient in this form of doubling.&nbsp; Your contention that the die face flattens with use is possible but cannot be corroborated.&nbsp; As far as I know, it&#039;s never been corroborated.&nbsp; In any event, a flatter die face should be even more effective at preventing metal from extruding laterally from the die recess (at least that&#039;s what I think you&#039;re getting at).&nbsp; The characteristic appearance of die fatigue is never related to unwanted movement of coin metal.&nbsp; It has everything to do with degradation and distortion of the design on the die face.&nbsp; I&#039;ve never heard of a &quot;rocking effect&quot; and if there were one, it would probably cause machine doubling, not die deterioration doubling.</p><p><br /></p><p>Every aspect of your explanation was completely off base, and yet you presented it as glaringly obvious fact.&nbsp; I think that&#039;s what irritated me.[/QUOTE]</p><p><br /></p>
