That is WAY too much time and money to not have some kind of insurance. As some have said, common thieves normally don't know much about cards and would probably walk right by them. I'm speculating that this has to be someone he knows or associates with or a friend of a friend type situation. I would check in with all pawn shops, card shops and auction houses in the area. Get more details about the cards out there and post them here and on all the other big trading card forums. I would post this on FCB, PSA, Beckett, SCF, SGC and other forums. The more eyes you have looking for clues the better your chances of finding the culprit/culprits. I wish your friend luck in finding and prosecuting this/these scum.
