Collection: Randy Johnson Cards and Memorabilia

Randy Johnson, the towering left-handed pitcher known as "Big Unit," spent much of his career with the Seattle Mariners and remains one of the most recognizable names in baseball card collecting. His rookie cards and memorabilia continue to draw interest from collectors who followed his rise from a hard-throwing prospect to a franchise cornerstone.

This collection centers on Randy Johnson's key rookie cards, including the 1989 Topps Traded #57T and 1989 Fleer #381, available in PSA 9 and PSA 10 grades. Also featured is an autographed Seattle Mariners 16x20 photo in a deluxe frame with PSA/DNA authentication, along with 2026 Topps Now cards marking the Mariners' retirement of his number 51, offered in Gold Foil, Black Auto, and Orange Foil parallels. Buyers should pay close attention to the grading company, PSA grade, and specific parallel or serial numbering noted in each listing.
