<p>[QUOTE=&quot;BJBII, post: 6329834, member: 112607&quot;]In my opinion, CAC does not evaluate TPGs.&nbsp; At least I have not seen anything to support that they do.&nbsp; They basically only offer an opinion on a previously graded coin.&nbsp; Not too different than if I sent a coin to more than one TPG, or the people posting here asking others if they think a grade on a particular coin was correct.</p><p><br /></p><p>By &quot;grading the grader,&quot; I mean a separate entity who may determine if the TPG has demonstrated the ability to evaluate a certain coin within standard industry-accepted guidelines.&nbsp; I do not think the various TPGs use identical and documented acceptance criteria when arriving at a grade.&nbsp; Each TPG uses its own.&nbsp; Plus I am unaware that they provide information on how they arrived at a particular grade for an individual coin.</p><p><br /></p><p>I think the TPGs should be audited by an outside party to determine if the TPG is using industry-accepted criteria, following its own procedures, documenting results, and demonstrating the proficiency to grade any particular coin.[/QUOTE]</p><p><br /></p>
