MLB game used ball signed by Reggie Jackson

I went to a White Sox vs. Yankees game recently and got a ball from one of the players during batting practice. I then went over by the White Sox dugout and was shocked to see that Reggie was signing autographs. I got in the crowd of people and managed to get the ball signed by Reggie. The ball is not in perfect condition at all since it was used in a game and in BP but the grass stains and scuff marks add to the elegance of the ball.
