<p>[QUOTE=&quot;calcol, post: 2471542, member: 77639&quot;]It&#039;s possible that PCGS laser-scans all high-end (and some not-so-high-end) coins submitted for grading to see if they are in their Secure database.&nbsp; They may do this even if the submitter hasn&#039;t paid for Secure service.&nbsp; If it&#039;s already there, they&#039;ll know it&#039;s a resubmission and what the previous grade was.&nbsp; If it&#039;s not there, it will be for the future.</p><p><br /></p><p>They&#039;re probably generating some very interesting data.&nbsp; It would include coins they&#039;ve seen before that are coming back as raw coins and coins in various holders.&nbsp; Might also be able to detect coins that have been dipped or toned significantly since last seen.&nbsp; Depending on how they use the data, the resubmit-until-it-goes-up game may seldom work.&nbsp; For example, if a grader sees a code that indicates a coin has been graded six times before,&nbsp; it&#039;s just possible they could be a little tougher on it.</p><p><br /></p><p>Cal[/QUOTE]</p><p><br /></p>
