<p>[QUOTE=&quot;GDJMSP, post: 1604790, member: 112&quot;]And PCGS seriously considered doing it again (the 100 point scale) about 4 or 5 years ago.</p><p><br /></p><p>As to the original question, you have to remember the history and development of the grading system. Sheldon wrote his book in 1948, but that book and that grading system only applied to cents - not any other coins. It wasn&#039;t until 10 years later that Brown &amp; Dunn came along, took Sheldon&#039;s idea (and that&#039;s all they borrowed was the basic idea) and adapted that idea to develop the first modern grading system for all coins. But they didn&#039;t use all the grades we use today. </p><p><br /></p><p>It was almost 20 years after that, 1977, that the ANA finally came up with their first book on grading standards. And even then they still didn&#039;t still didn&#039;t use all the grades we have today. They used AG3, G4, VG8, F12, VF20, VF30, EF40, EF45, AU50, and AU55. And in MS grades there were only 3 grades - MS60, MS65, and MS70. </p><p><br /></p><p>Then it was another 10 years (1986) until the ANA changed their grading book, adopted the market grading system, and came up with all of the grades we use today. The TPGs copied the ANA&#039;s system, and developed their own sets of grading standards, which they further changed over the years. They didn&#039;t change the number of grades used, they just changed the standards on which those grades were based.</p><p><br /></p><p>To put that into perspective, for the first half of my life there were only 3 MS grades - 60, 65, &amp; 70. That&#039;s it.</p><p><br /></p><p>I suppose the first suggestions about increasing the number of grades first started about 10 years ago. There wasn&#039;t much talk about it back then, but there was talk. Then like I said, about 4 or 5 years ago PCGS held company discussions and seriously entertained the idea of adopting the 100 point grading scale. There were lots of articles about it written in the coin mags and lot&#039;s of discussions on the coin forums. Most were against the idea. And once that became known PCGS dropped the idea. A couple of years later, here come the plus grades.</p><p><br /></p><p>So I suppose it is only a matter of time until the entire system is changed yet again. And undoubtedly we will end up with more grades than we have now. History tells that is pretty much inevitable.[/QUOTE]</p><p><br /></p>
