<p>[QUOTE="Morgandude11, post: 1996858, member: 37839"]Most Morgan DMPLs are slabbed. The collectors that originally bought them wanted that designation, and got it, as TPGs can recognize an altered Morgan. Doug is correct--there have been many ways that Morgans have been altered to look DMPL and PL--simple shining and polishing with an abrasive polish and buffer is the simplest way--it may make it look more reflective, but the abrasion on the surface is unmistakeable. One can see the hairlines (unusually in a circular pattern) from buffing, as it destroys the metal on the surface of the coin. Sandblasting (as mentioned by Doug) is another familiar way--the tell-tale mark of this treatment is having a pitted surface. Acid etching is also quite common--since the acid removes the top layer of the surface of the coin, one ends up with a coin looking bright, shiny but lusterless (this is not a contradiction---the original mint luster is very characteristic, as opposed to a falsely shiny surface, which has a dull, lifeless quality to it).[/QUOTE]</p><p><br /></p>
