That sounds like a great idea to me too. I'm all for the whole supply/demand thing. It's the American way!
I don't know so much about it being the "American" way, but it sure sounds like the "If-it-were-my-card-for-sale-I'd-want-the- best-price-I-could-get-for-it" way. And just what would I do with all the $$$$$?

Buy more cards, of course.
Otherwise I'd just put it on Diagon Alley and say- Who wants it, PM me and I send it to you and I'll even pay the postage.
