NR: McGwire 1998 Game Used Signed Ball Hit PSA
 

Allegedly hit by McGwire during the 1998 season for foul ball. Signed later by Big Mac. You can see the barrel marking.

Unfortunately I don’t have provenance other than it was acquired from a respected source. Moving due to acquisition of another Ball.
