I've got an idea. Go to a pawn shop.. and pretend like your going to sell it to them. Say: "I don't know who's autograph this is.. maybe you do?" and then you can make up some lie about "Oh yeah, my grandfather gave it to me saying it was his best autographed ball he had" something like that. The guy at the desk might know, but if he doesn't, he'll bring in somebody who thats there job, to look at signatures. Then when they tell you, Just say "You know, I changed my mine cya" LOL!
