If I remember correctly reading somewhere that he had a "box" of them. So rack or few racks, I wouldn't know. Considering they are NCV chips most of the time they aren't cancelled because they have no value. Many times all the NCV chips stay together, but I'm not sure in this case. I've seen too many of these sold on eBay recently to be paying some astronomical price for a single.
If I had the chance I'd probably pay $50 for the set of three, but that's my opinion.
