What a goldmine! A Slabbing Authentication Service! Just send your slabbed cards in to be sure they're legitimate and we'll check to make sure we really slabbed them in the first place! I'm sure the slabbers are already working out their fee structure for this service. These guys can make fees over and over again from looking at the same cards!
