<p>[QUOTE=&quot;GDJMSP, post: 4219149, member: 112&quot;]Oh there was all kinds of discussions about grading going on in the 50&#039;s. But what a lot of folks don&#039;t realize is that those discussions had been going on since about 1898. And even then it was among the ANA, founded in 1891, members that it was being discussed. And this is discussed in some older copies of the <i>Numismatist</i> that I have from 1915,&#039;16, &#039;18, and &#039;19. </p><p><br /></p><p>As for the Sheldon Scale, while <u>the general idea</u> of the Sheldon Scale was eventually adopted, for the 1st time in 1958 by Brown &amp; Dunn - </p><p><br /></p><p><a href="https://www.pcgs.com/news/part-four-martin-brown-and-john-dunn-1958-the-first" target="_blank" class="externalLink ProxyLink" data-proxy-href="https://www.pcgs.com/news/part-four-martin-brown-and-john-dunn-1958-the-first" rel="nofollow">https://www.pcgs.com/news/part-four-martin-brown-and-john-dunn-1958-the-first</a></p><p><br /></p><p>- the Sheldon grading system itself was not adopted as that applied to large cents only. But yeah, it was Sheldon who gave everybody the basic idea of a numerical grading system.</p><p><br /></p><p>It was not until 1977 that the ANA expanded on the work of Brown &amp; Dunn and published the 1st edition of their grading standards. And in that edition there were only 3 MS grades - 60, 65, and 70. </p><p><br /></p><p>In the years that followed the MS grades of 63 and 67 were added in the 2nd edition. But it was not until 1986 that the ANA invented and switched over from the technical grading system to the market grading system - which included all the MS grades from 60 to 70. That 3rd edition was published in 1987. And it&#039;s no coincidence that PCGS and NGC were founded those same 2 years as the men who started both companies, contributed to that 3rd edition.</p><p><br /></p><p>Today, they are on their 7th edition which was published in 2013 I think it was. But other than 2 specific circulated grades, 1 each for 1 specific coin, one a Buffalo nickel the other an IHC, it remains the same as it was in 1987.[/QUOTE]</p><p><br /></p>
