davidcyclebackI wouldn't be surprised if a Madonna single signed baseball might be worth over $100.
Actually, a baseball signed by the cast of a movie, any movie, is uncommon. If the signatures are authentic, this is not a common item.
I remember the episode of South Park where Rosie O'Donnell visits the elementary school class and the teacher says, "Run kids! I'll try and fight it off!"
