The product is a Mark McGwire signed baseball with authentication from James Spence Authentication (JSA). This original autographed baseball features the signature of the former Oakland Athletics player, who is a Hall of Famer in Major League Baseball. The item is a genuine collectible for fans of the sport and the player, making it a unique and valuable piece for any baseball memorabilia collection.  Originally purchased from Pristine Auction back in 2022 and due to financial reasons, I need to give it a new home.
