guys, i found an old autographed baseball from when "rick cerone" played baseball. (i can't remember if he played for the yankees or a mets). anyway, i have this ball that was autographed by what looks like the entire team from back then. (players like graig nettles, reggie jackson, lou pinella, etc.) it's kinda beat up, and some of the names appear to be smeared. does anyone know what this could be worth, and how do i find out? (it's gotta be at least 30 years old or more). i remember being a member of the rick cerone fan club then. i guess i was about 8 or 9 back then.
