Let me explain my comment. If the problem is that wrinkles may have been pressed out through a partial lifetime in a screwdown holder, that's something that PSA considers Altered Stock that I believe would/could pass the other TPGs. PSA is known for being tough on this particular alteration.

Here's a card that was given "Altered Stock" by PSA and holdered as an SGC 60, but was originally a BVG 6.5.
If the alteration is something else detectable by black light, I would figure all of the three should be able to identify that.
