Official National League (Giamatti) baseball signed by Hall of Fame pitcher Sandy Koufax. This ball differs from most Koufax singles in that Koufax has scripted his full first name, "Sanford," instead of the usual "Sandy." Koufax's signature has been scripted in blue ink across the sweet spot and grades 7/10. The ball displays light age spotting and is otherwise in Excellent to Mint condition. Full LOA from PSA (with corresponding hologram label affixed to the ball).
