I have a Cal Ripken Jr. foul ball that I got him to sign, and like Tony said for whatever reason, it is almost completely faded away. It has been kept in a UV case, not in any light the whole time.

That said, it is a GU ball, I would probably get it signed. I dont know what other type of pen besides ball point would be good on a ball though. Definately use a blue ball point, not black.
