Collection: Zac Gallen Rookie Cards and Signed Memorabilia

Zac Gallen is a right-handed starting pitcher for the Arizona Diamondbacks, and his 2020 rookie card season remains the focal point for collectors tracking his early career. Rookie-year cardboard from that debut season carries added interest for those building out a Gallen collection or a broader Diamondbacks rotation set.

This collection centers on 2020 Topps Chrome rookie cards, including the base #132 Rookie RC, the Prism Refractor and Xfractor parallels, plus a 2020 Topps Bowman Chrome #81 rookie and a 2020 Topps Complete Set Gold Stars #207 rookie. Most pieces here are PSA 10 Gem Mint graded, and there is also a signed Donruss Optic rookie autograph card graded by BGS. Buyers should note the specific parallel (Prism Refractor vs. Xfractor vs. base Chrome), the grading company and grade, and whether the card carries an on-card autograph before comparing pieces.
