PSA has a good thing going there since at the time the ball is graded after it tones now it's your problem and not there's. That ball grading always to me seemed to be a joke.

The same issue applies to CGC slabbed comics, which indicate paper quality. Some comics are also prone to slide around inside the shell damaging corners. So, you can end up with a book in much lower grade than the label indicates. The conventional wisdom is those books will never be cracked from the slab.
