IMO, I believe "Mr.X"'s true identity could be Billy Crystal. Other than Charlie Sheen, Billy Crystal is the only other Hollywood celebrity that I know of, who collects baseball memorabilia. After all, Billy Crystal did plunk down $200K, for a Mantle game used glove from the 1960's at the Barry Halper auction, back in 1999.
Best Regards,
