Dear lucky SOB
Ok,in addition you also have:
Ron Guidry
Bucky Dent
Lou Pennela
THURMAN MUNSON $$$$
that I can read on the one ball, probably the '78 world series team. All those guys are/were stars (maybe not Dent) Thurman Munson, died in 1979, so his autograph is very rare
The Ted Williams ball, now that he passed, is worth a fortune, you may just want to hang onto them, I really doubt their value will diminish. Chances are as those other players pass on, the value will skyrocket. Keep them, the day Reggie Jackson passes away you will be thanking me....
PS - Keep the balls

Do not play catch with them either...LOL
