Let's say a card corner has been restored - one corner only, and that trimming was not involved. How do the major grading companies check for this? (i.e-paper restoration). Does the black light catch this, or does it take paper-fiber analysis with a microscope? Or is it non-catchable?

This leads to a follow-on question: if you CAN catch corner restoration, what is an acceptable failure rate? Are the grading companies meeting an acceptable rate?
