Obviously this topic has been discussed many times before, but due to his frustrations, Jon English Antique Sports & Cards put his money into conducting his own research and he presents the results. Here's a link to the YouTube video titled Changes to PSA Grading, Part 2:

Jon has been submitting cards to PSA grading since 2008. He feels that PSA grades from 10 years ago are completely different than they are today. He feels PSA has totally changed their grading standards and that they should really start a new registry. To prove his point, he bought older examples of PSA graded cards in high grade and compared them to cards he submitted that were basically from vending. Then he cracked out the old PSA graded cards and resubmitted them to PSA to see how they would grade today. Watch the video to see the results. Comments?
