James Dean's "Rebel Without a Cause" T-shirt--start the bidding at $15,000

The white, cotton T-shirt with the $15,000 price tag has a Hollywood pedigree, having once hugged the torso of actor James Dean during the filming of "Rebel Without a Cause."

That makes it a valuable collectible to some of the quarter million registered customers who could bid on it during online auctions scheduled for Friday and Saturday.
