Mickey Mantle + Bobby Brown On same ball value?
 

Well, I've tried to search multiple combinations of the words but all I can bring up is "Mickey Mantle auto bobby brown ball".

Does the bobby brown + mantle add any additional value?

Here is photos of the ball...

I would say no, Brown was a low level player on the Yankees, and most Yankee team balls from that era have his signature on them. I can't make out the 3rd signature, but unless he is a notable player, I would not imagine any increase on value over other Mantle multi-signed balls, which are usually valued lower than a single signed.


On a side note, I believe the Mantle signature to be authentic.
