<p>[QUOTE=&quot;Oldhoopster, post: 3224192, member: 84179&quot;][USER=42872]@Rick Stachowski[/USER] I&#039;m having trouble trying to understand how a raised rim around a hole could be anything other than PMD.&nbsp; Even if was a strike through, how would the edges be raised?&nbsp; The striking pressure would keep the field flat.&nbsp; The metal is obviously malleable, so that rules out stress induced brittleness.&nbsp;&nbsp; Maybe of an object was pressed into the planchet and did not deform during striking and was subsequently pulled out leaving a raised rim, but I really think that is pretty unlikely.&nbsp; Hope I&#039;ve explained why I think it&#039;s PMD[/QUOTE]</p><p><br /></p>
