<p>[QUOTE=&quot;K Porter, post: 4992732, member: 115815&quot;]- - - - -</p><p>Thank you for all the nice welcomes. Thank you for your response. Very nice of all of you. - - - </p><p>I&#039;m trying to envision knife cuts where the displaced metal could wear down and fill in the&nbsp; negative space on a lightly circulated XF/AU bust quarter and I&#039;m having a difficult time doing that. Would not the displaced metal have to be dramatically even and equal on both sides of the &quot;divot&quot; to wear &amp; recover evenly to fill it in so thoroughly? Would it not need substantial friction and time? Could the mass of displaced metal fill in and exceed the volume of the negative space? The elevated ridges on the seated half are substantial where they overlie the olive leaves. If one was to &quot;evacuate&quot; the ridges, would negative space remain under the linear metal mass? - - - Just some food for thought. I do have some metallurgy and physics buried in my brain mixed in with the numismatics...so I&#039;m trying to envision knife cuts where the displaced metal can so &quot;nicely&quot; fill the void...especially on a lightly circulated coin.[/QUOTE]</p><p><br /></p>
