The document which banned Pete Rose from baseball is up for auction:
Now, Rose’s personal copy of the 1989 agreement—the only other original copy belongs to Major League Baseball—is being put up for bid by Goldin Auctions. In addition to Rose’s autograph, the pact features the signatures of Rose’s attorney, Giamatti and Fay Vincent, the deputy commissioner who ended up succeeding Giamatti.
Bids start at $100,000, and the auctioneer estimates the document could fetch between $500,000 and $1 million.
I presume the varied amounts are a function of the uncertainty of the condition of the document itself. Because based on the way Rose has carried himself since 1989, I could see the document being in pristine condition due to Rose never having read it, or I could see it being totally soiled after he repeatedly wiped his butt with it.
