<p>[QUOTE=&quot;imrich, post: 2061015, member: 22331&quot;]If you want to learn about grading disparity, I suggest you ask your library to obtain a copy of the Coin World &quot;year long blind grading study&quot;. It was available in the past on the internet, but it appears that &quot;influence&quot; has allowed the article to be &quot;blocked&quot; with only minimal reference.</p><p><br /></p><p>A search using the phrase:</p><p>&quot;Third-party_grading&quot; will allow a brief overview where there was a 7 grade disparity between TPG.</p><p><br /></p><p>You have referred to a 4 point grade disparity between a &quot;self slabber&quot; and one of the&nbsp; &quot;top tier&quot; TPG. I believe that can be readily established between the 4 top tier TPG with the current differing &quot;market grading&quot; systems.</p><p><br /></p><p>I believe to have the graded components which would readily establish, by an independent authority, a 4 point grade spread between the 4 &quot;top tier&quot; TPG.</p><p><br /></p><p>I believe the current &quot;top tier&quot; grading system can be shown to have the same degree of grading disparity you&#039;ve selectively documented.</p><p><br /></p><p>JMHO[/QUOTE]</p><p><br /></p>
