In what proves to be one of the most rare signings ever, this pair of Jordan 2010s up for auction should go for a considerable amount of money. It's not often that Tinker Hatfield and Michael Jordan sign a pair of Jordans, let alone one from from Michael's own personal collection. According to the auction site, this is the only pair of sneakers signed by both Jordan and Hatfield — and while that may be an exaggeration, all proceeds of the auction will go to Portlands' Ronald McDonald charities. Head over to the site now, you only have until tomorrow to bid. [via Ronald McDonalds House Charities]
