1 MILLION dollars!
Its worth about 1,000,000 it depends on the condition of ball and if the ball is a nba certified or not nba certified ball signed will be worth more
I say a Lou Brock signed ball is probably worth at least a hundred bucks.But it depends on how old it is.
depends who signed it
The George best autogragh is worth about $100( That's what I sold one for). If he had signed a Manchester United ball , It probably would be worth more. maybe $200. if it was a man utd ball that was signed by him while in his playing days at utd, it could be worth a lot , lot more. He Lived in Chelsea for a good while , that's probably were the ball was signed. Good luck
about £400 - £600
its worth about 16000$
