<p>[QUOTE=&quot;Conder101, post: 2453109, member: 66&quot;]As stated in the OP the question has no sensible answer.&nbsp; It isn&#039;t measuring consistency it is asking &quot;If I sent in 100 coins graded MS-65 to my theoretical standard, how many would the TPG agree with?&quot;&nbsp; If you are wanting to measure consistency you send them 100 MS-65 coins that they have previously graded (from the same generation holder so there won&#039;t be possible deviations from different grade standards assigned at different times) and see how many of the 100 come back at the same grade.&nbsp; From the results of the professional graders results in past PCGS World Series of Grading contests it would probably be in the 80% range or so.[/QUOTE]</p><p><br /></p>
