barrysloateJim- perhaps a more practical plan would be for you to review a portion of your collection and pull out 50 cards that even you feel don't look quite right, and submit that group to SGC for review.
It's silly to suggest that Jim ship all 25,000 slabs but a sample would be a pretty good litmus test. And if a high percentage of those are deemed altered, say 10 or more, I would be having a long and hard talk with PSA. And if they turn out to be fine, mission accomplished.
