<p>[QUOTE="Insider, post: 2296679, member: 24314"]Yeah, yeah, we all have a story to illustrate a point of view - there are exceptions to everything. James Halperin did the same thing to a Bust dollar long ago. Unfortunately, stories from several years ago don't hold water because the TPGS have become more sensitive to alterations - good or bad - that raise or lower eye appeal.</p><p><br /></p><p>Toning (oxidation) happens in degrees shown by color. When the color of natural oxidation is black - the surface is gone - etched period. I have never seen an exception. I feel qualified to say this because one of my nicknames at a particular organization was "Dipper." The coin above may have looked OK. Perhaps the formerly toned surface was "worked on" by professionals after the toning was removed but I'll guarantee that under a microscope the surface showed evidence of etching or its possible restoration to improve the look. Unfortunately, most don't examine coins closely or are ignorant of characteristics found on an etched coin's surface. Besides, in spite of the oxidation removal the TPGS determined the coin was market acceptable as an MS-66. As you have written before in many posts, that does not mean you would agree with the assigned grade.[/QUOTE]</p><p><br /></p>
