<p>[QUOTE=&quot;GDJMSP, post: 5411686, member: 112&quot;]We&#039;ve talked about the difference, and the time line, between technical grading and market grading before. In simple terms technical grading is what was used before 1986, and market grading is what was used from 1986 onwards. The ANA created the market grading system and the TPGs merely copied its basic principles. But they did not copy the ANA grading standards. The grading criteria being used by both were the same, but the TPGs relaxed (made more lenient) the qualifications required for each grade. And the TPGs also decided that, under their system, coins with wear could be graded as MS. Under the ANA system coins with wear cannot be graded as MS.</p><p><br /></p><p>Also, the TPGs use grades to assign value, whereas the ANA standards describe and define condition. </p><p><br /></p><p><br /></p><p><br /></p><p>When you say &quot;stuff&quot; I can only assume you mean grading criteria. The TPGs relaxed ALL the grading criteria beginning in 2004. All of it, across the board. There are about 9 or 10 different criteria, but the 4 primary ones are luster, eye appeal, contact marks, and hairlines.[/QUOTE]</p><p><br /></p>
