NickMI've done it.
I sent 5 cards in that I was confident had been overgraded and explained with the submission that I was sending them back for review because they were overgraded. PSA agreed with me on all 5, sent them back to me properly graded, and sent me a grading voucher for the value difference.
FWIW, 4 of the cards had back issues that had been missed (1 wrinkle, 1 pencil mark, and 2 miscuts), while the other didn't meet centering standards for the original grade.
