<p>[QUOTE=&quot;-jeffB, post: 1967746, member: 27832&quot;]It&#039;s not just a grading <b>racket</b>, but a grading <b>ratchet</b> -- as long as you keep reconsidering/crossing it instead of cracking it out, it can only go up, never down.</p><p><br /></p><p>So, if there&#039;s a 5% chance that it will upgrade, and it costs $100 each time you try, but the bump in value is much higher than $2K, the numbers say that you should keep resubmitting until it bumps. Eventually, most such coins will have been resubmitted enough to reach the highest grade that they can possibly justify. And at that point, well, it&#039;s time to &quot;renormalize&quot; the grading scale based on existing populations... but until then, rational actors will keep doing the rational thing.</p><p><br /></p><p>For the coin in this thread, [USER=43130]@C-B-D[/USER] and others correctly judged that the odds were much, much better than 5%.
