How much would you say this MMA figure is worth?

My husband and I come upon a very interesting find at Toys R Us. We found a Royce Gracie figure in a box with his picture on it but Kimbo Slice's name on it. I've searched the web hig and low and have yet to find anyone that seems to have one of these misprints. It actually looks like someone put the wrong name card in the packaging but without opening the item it is hard to tell exactly how the name plate is attached. It was certainly the only one in the store. It reminds me of the beanie baby crazy where people send thousands over a ladybug missing spots (or whatever the issue was).
