<p>[QUOTE="Abramthegreat, post: 8452853, member: 136180"]You guys are probably right, but I thought I might as well share something I found that is similar: <a href="https://www.error-ref.com/collar-damage/" target="_blank" class="externalLink ProxyLink" data-proxy-href="https://www.error-ref.com/collar-damage/" rel="nofollow">https://www.error-ref.com/collar-damage/</a></p><p><br /></p><p>"The upper member of these two 2008-P New Mexico quarter dollars displays unusually wide, flat valleys between the reeds, with the valleys carrying heavy horizontal scratches. This appearance reflects the fact that the ridges on the working face of the collar were abraded and truncated. Similar damage is known from other dates, including 2007-P Wyoming quarters. This damage may have been produced when the beveled entrance of the collar was being machined or de-burred. The rotating machine tool may have slipped into the functional portion of the collar, damaging the reeding."[/QUOTE]</p><p><br /></p>
