<p>[QUOTE=&quot;GDJMSP, post: 2019500, member: 112&quot;]Paul, I have said many times that the TPGs have changed their graded standards several times, not just once. You mention above the change when they stopped using the &quot;rattler&quot; slab. That their standards were loosened then. But what the OGH, the old green holder ? Is it not the market&#039;s perception that the TPGs also loosened their grading standards when they stopped using the OGH ? Is it not and was it not for many years the market&#039;s perception that coins in the OGH would be upgraded by PCGS if cracked out and resubmitted ? Seems to me you&#039;ve even agreed that was so yourself. But do you know when that change took place Paul, or do you deny that it happened ? That there was no change, no loosening of grading standards ? Well, just so you know, that change, and pretty much the entire market agrees there was a change, that change took place in 1998. That&#039;s how long the OGH was used. And that is documented in Conder101&#039;s book.</p><p><br /></p><p>So that would make at least 2 times that PCGS changed/loosened, their grading standards wouldn&#039;t it ?</p><p><br /></p><p>No as for this book by James Halperin that you mentioned as being written in 1985 - do you mean this book ? </p><p><br /></p><p><a href="http://www.amazon.com/exec/obidos/ASIN/0933372027/jameslhalpe" target="_blank" class="externalLink ProxyLink" data-proxy-href="http://www.amazon.com/exec/obidos/ASIN/0933372027/jameslhalpe" rel="nofollow">http://www.amazon.com/exec/obidos/ASIN/0933372027/jameslhalpe</a></p><p><br /></p><p>The one that was not published until 1990 ? And yeah Paul, I have an original copy even signed by the author, and it&#039;s copyright is 1990, just like the one found at that link above. Four years after market grading had been invented. So it would be kind of hard for it to be - </p><p><br /></p><p><br /></p><p><br /></p><p>- don&#039;t ya think ? Seeing as how they both existed for 3 and 4 years before the book was even published ?</p><p><br /></p><p>But you are correct about one thing, James Halperin played a big part in developing market grading. His name is among the first listed in the ANA book as being essential to the development of market grading. He helped write it.[/QUOTE]</p><p><br /></p>
