Sandy Koufax Signed Baseball. JSA

The Left Arm of God!

Presented here is a classic signed baseball from Sandy Koufax, widely regarded as one of the greatest pitchers in the history of baseball. Koufax’s brief but unparalleled peak defined by dominance, precision, and historic postseason performances has secured his legacy as an all-time icon of the game.

This example features a clean white baseball signed in blue ballpoint ink, with outstanding contrast that highlights Koufax’s highly recognizable autograph. The signature is placed on an Official National League baseball bearing the stamp of Bart Giamatti, further enhancing the piece’s period authenticity and collector appeal.

A timeless Hall of Fame autograph and a true cornerstone piece for any serious baseball or pitching-focused collection.

Accompanied by a full Letter of Authenticity from James Spence Authentication (JSA).
