If you were to sell it as a set, I'd would expect it to sell for about $750-$1K (tops) on eBay. You would probably get a little more for it in person, since people can check each card out individually for condition and patch quality, and if you were to piece it out, you'd likely do better than selling as a set. For whatever the reason, Hot Prospects just wasn't widely well received, and while there are a couple key cards in there, other than the Crosby and Ovy, the rest of the key cards wouldn't attract much attention due to the patch pieces (Lundqvist, Perry, Getzlaf, Vanek, Carter, Richards, Phaneuf, Parise).
Good luck with the sale though. It's one set that I have considered building on more than one occasion, although I am not willing to attempt it until I am done the 07-08 set. Great job on completing it.
