Hi, I recently purchased a signed baseball that I know nothing about. The ball appears to be older and quite dirty with several signatures on it that I can't make out. Whats the best way to go about finding out who signed it and how old it is. I have the original box that it was sold it, but there is no indication or markings on the box of what company made the ball, just a generic picture of a baseball player on it. I can send images of this if anyone is interested.
