Marc S.Here is PSA's:
"Grading involves individual judgments that are subjective and require the exercise of professional opinion, which can change from time to lime. Therefore. PSA disclaims any warranties, express or implied with respect to the grade assigned to any card, as well as any liability whatsoever to the card's owner or submitter, except pursuant to PSA's guarantee resubmission policy then in effect."
To me, it is implied that it is their professional opinion as opposed to 100% certainty. Most people in this hobby, I think, take that as part of the game when they buy and/or sell graded cards.
