I've been curious about the value also. I've been putting together a nice collection myself. I do know that they are legit autographs though because they have the authenticity stamp right on the card. The first one I bought was Frankie Edgar on EBay, but since I have bought a ton of packs and gotten many more. Part of me wants to sell them for some cash, but I can't help but feel like if I hold onto them they will be worth much more down the road. It's almost like having old school baseball cards like Babe Ruth, Micky Mantle, etc. The sport is so young in the grand scheme of things.
