ONE HAMMERED ON TELETRADE FOR 3500.00!!!!!!! YOW!

Hi! I'm GERBILKEEPER. Just wanted you guys to know that I'm new on the scene, and I'm just getting aquainted to this whole collector's society thing. (which I think is kind of cool) Anyway, I was wondering if anyone has any thoughts on my SUPERCOIN: 1981-S sba TYPE 2 pcgs pr70DCAM....WITH ONLY 34 PCGS POP., is it possible to get BIG BUCKS (at least pcgs price guide price) for this coin? I would assume that in order to assemble a perfect set of SBA proofs, you would need this coin. Therefore, is there really a demand in which I would be holding the ball in my court? Bottom line: Are there people out there who seriously would pay retail or higher for this coin? Thanks, Your feedback would be appreciated
