<p>[QUOTE=&quot;Conder101, post: 3722851, member: 66&quot;]Sample size is really too small to come to any real judgement, not enough data points.&nbsp; If you want to make a really valid test send the same coin to each TPG a few dozen times at each tier level, with and without attribution and then plot the results.&nbsp; To make it an even more valid test do the same thing with a group of coins at different grade levels and different series.[/QUOTE]</p><p><br /></p>
