<p>[QUOTE=&quot;calcol, post: 4198890, member: 77639&quot;]I&#039;ve looked at lots of PCGS-slabbed coins and only last week noticed that recently issued slabs are lettered on the edge of the narrow end nearest the coin.&nbsp;&nbsp; It always seems to be seven letters.&nbsp; At first, I thought the lettering was in white ink.&nbsp; But when I took pictures (see below), it became obvious that it was&nbsp; physically etched with either a laser or sharp point.&nbsp; The lettering can vary in its left-right position on the edge.&nbsp; The letters are not unique to a coin.&nbsp; I have some slabs with the same lettering.</p><p><br /></p><p>Some (all?) older slabs have an edge that is too narrow for this type of lettering.</p><p><br /></p><p>Anyone know the purpose of the lettering?&nbsp; I&#039;m supposing it could be the source/lot of slab material, date of slabbing, anti-counterfeiting measure, person doing the slabbing, grading location, or slabbing machine&nbsp; ... or a combo of the above.</p><p><br /></p><p>Cal</p><p><br /></p><p>[ATTACH=full]1077281[/ATTACH][/QUOTE]</p><p><br /></p>
