Fielding offers on this amazing Alpha set from Magic: The Gathering, 3M USD$ OBO. For the past 13 years that I've owned it it has been recognized by PSA as the most mint set they've graded, and prior to my ownership it was also the top graded set by the previous owners.
I know it is a long shot but as mtgox did evolve from a mtg trading website, I figured I'd tap into history a bit and post it here.
