<p>[QUOTE=&quot;Conder101, post: 1004827, member: 66&quot;]They did back in 1990/91 (The Expert System) and decided it didn&#039;t work well enough.&nbsp; Coin World had an excellent article, I believe it was last week, that looked back at th entire experiment of computer grading that took place back in the late 80&#039;s early 90&#039;s.&nbsp; The &quot;New&quot; PCGS Secure Shield program that they introduced this year is actually the first part of what they were doing back in 1990.&nbsp; Scanning the coin and creating a digital fingerprint that allows the coin to be recognized again if it is ever resubmitted thus allowing the same grade to be applied resulting in consistency in the grade. When computer grading failed back in 1991 I recommended that they scrap the grading part but keep the scanning to provide consistency and eliminate the crack out game.&nbsp; Twenty years later they do just that and tout it as something new.[/QUOTE]</p><p><br /></p>
