<p>[QUOTE=&quot;calcol, post: 2795213, member: 77639&quot;]I think few folks dispute a grade on a coin that they submit that comes back graded higher than they expected.&nbsp; Perhaps they would for an obviously worn coin that comes back with a MS grade.&nbsp; So, how often do wrongly high grades appear on slabs?&nbsp; The TPGs may have run some quality assurance tests to monitor it, but if so, I doubt the results will be made public.</p><p><br /></p><p>I suspect this kind of error is uncommon, especially for high-end coins that may get extra scrutiny by finalizers after slabbing. Still over time, it probably does contribute a little to gradeflation.&nbsp; And it&#039;s one more reason to look at the coin and not just the slab label when buying.</p><p><br /></p><p>Cal[/QUOTE]</p><p><br /></p>
