As a part of my job, I inspect cards for authenticity. Obviously, all raw cards are looked over to a degree (naked eye, loupe, halogen light, etc), but I have seen examples of cards that have been altered recently in a way that is obvious to the naked eye, yet they still reside in a holder from one of the "Big 3".

My question is two-fold:
1. Which of the grading companies (if any) can I trust to spot an altered card?
2. Is there any trust given recent events or in general, or should I simply inspect all graded cards the same way I would raw cards?

Thanks in advance
