Bob Gibson Signed Baseball

A Bob Gibson signed baseball is the essential collectible for anyone building a Cardinals collection or honoring the history of MLB pitching. Gibson's 1.12 ERA in 1968 — still the modern-era record — makes his signature on an official Rawlings baseball one of the most meaningful in the hobby. With Gibson having passed away in October 2020, authenticated signed baseballs from reputable third-party partners are the definitive standard for collectors. Pristine Marketplace carries 38 authenticated Gibson signed baseballs, including flat-signed ONL and OML examples and inscribed editions featuring "1968 NL MVP," "HOF 81," and Cardinals-specific inscriptions.

Every signed baseball is authenticated by Pristine Authentic and/or our third-party partners (PSA, JSA, Beckett), with COA and tamper-evident hologram included. Covered by our 60-day return policy.
