Mickey Mantle was a rare talent - and so are the inscriptions on these baseballs signed by the Triple Crown winner and Hall of Famer. They include: "HOF '74" and full name "Mickey Charles Mantle." The Official American League baseballs (Brown) rate a 7.5, while the signatures average 8.5. Each ball comes with its own PSA LOA. Widely regarded as the greatest switch-hitter in baseball history, Mantle played his entire 18-year career with the New York Yankees.
