<p>[QUOTE="Lehigh96, post: 1913632, member: 15309"]The argument that I made about strike can easily be made about high point friction. Almost all St Gaudens double eagles exhibit friction on the high points of the design. Without allowing for roll friction, the TPGs would be forced to grade every coin an AU coin. The result would be that this coin:</p><p><br /></p><p><img src="http://i117.photobucket.com/albums/o59/ACPitBoss/Roll%20Friction/Saint1908PCGS_zps2ada6cd2.jpg" class="bbCodeImage wysiwygImage" alt="" unselectable="on" /></p><p><br /></p><p><img src="http://i117.photobucket.com/albums/o59/ACPitBoss/Roll%20Friction/Saint1908PCGSleg_zps9c4ddf49.jpg" class="bbCodeImage wysiwygImage" alt="" unselectable="on" /></p><p><br /></p><p>would be graded the same as this coin:</p><p><br /></p><p><img src="http://i117.photobucket.com/albums/o59/ACPitBoss/Roll%20Friction/Saint1908NGC.jpg" class="bbCodeImage wysiwygImage" alt="" unselectable="on" /></p><p><br /></p><p><img src="http://i117.photobucket.com/albums/o59/ACPitBoss/Roll%20Friction/Saint1908NGcleg.jpg" class="bbCodeImage wysiwygImage" alt="" unselectable="on" /></p><p><br /></p><p>The TPGs need to be able to differentiate coins of different quality. When rules are made that limit the grade of coins, it inhibits their ability to differentiate quality and necessitates the need for exceptions to the rule. Roll friction is an exception to the rule that wear relegates a coin to an AU grade. In practice, the TPGs look for friction in the fields of a coin in order to deem a coin AU. High point wear does not condemn a coin to AU status. Now you might not like it, but if you collected Saints, you might be very quick to change your mind.[/QUOTE]</p><p><br /></p>
