Peter SpaethI continue to doubt the permanence of these supposedly undetectable changes. I have seen Cracker Jacks warp significantly inside their slabs -- obviously even though they may have "dried" flat they did not retain their shape. I have seen corner flips that either reappeared or were missed the first time -- the latter I consider unlikely. I have also seen wrinkles on cards graded 7 or higher although who can say if they reappeared or just were missed during the grading process -- including a PSA 7 T205 Matty that had prominent wrinkles if you held it at the right angle.
