Value isn't a term typically bantered about by collectors. Value for such enthusiasts exists on a different plain. If something's a must-have, then they must have it, and that's the value. Take, for example, these special edition Nike Hyperdunk basketball shoes. Nike's only making 500 pair, and they're already trading for as much as $700.
So what makes these so special? Not the shoes themselves, but the feat they supposedly represent. A couple of years ago NBA all-star Kobe Bryant appeared in a video for Nike in which he appeared to have jumped over an Aston Martin roadster that was speeding right at him. In the middle of the playoffs, no less. Bryant looked to have cleared the car, and people went nuts. Of course it was all camera tricks, even if he actually is capable of theoretically pulling it off.
That's what these shoes celebrate. They've got Kobe's signature embossed on the inside of the tongue, and Aston Martin's winged logo on the outside. Are they worth seven bills? Well, that depends... to who?
