I happened to stumble upon something on their website this morning and it lead me to view another item that I just had to chuckle about. The common Steve Balboni that they had listed, signed, for $499. It isn't just him though, it is every item they have ohm their site. I'd say that tops the Terry. At least Terry is a HOFer and is deceased and there is some demand for his signature.
