The 500 Home Run Club multi-signed baseball is among the most prestigious collecting categories in all of sports memorabilia, and this example — carrying 10 signatures — delivers a remarkable assemblage of the game's all-time power hitters. Headlining the ball are Mickey Mantle, Willie Mays, and Hank Aaron — three of the greatest sluggers in baseball history and three of the most coveted signatures in the hobby. Joining them are additional 500 HR Club members including Harmon Killebrew, Frank Robinson, Ernie Banks, and Reggie Jackson, among others, all signing on an Official American League (Bobby Brown) Rawlings ball.

The signatures appear in blue ballpoint ink across the white leather, with each name clearly legible. Mickey Mantle's sweeping, characteristically large signature anchors one panel while Willie Mays and Hank Aaron — the second and third greatest home run hitters in baseball history — appear on adjacent panels. Accompanied by a JSA Letter of Authenticity. With ten signatures from baseball's most exclusive power-hitting fraternity, this ball represents a landmark multi-signed piece for advanced collectors.
