It sucks, but it happens. I think my worst incident was two or three years ago when I was cracking out my graded '53 cards to put the set in an album. I was watching tv while doing it and got sloppy. The screwdriver slipped and my formerly PSA 3 Jackie Robinson got hit. I was almost done too. I got a little gun shy after that so the two remaining cards (Mantle and Paige) remain graded.
