The 1989 Upper Deck Ken Griffey Jr. is one of the most beloved and iconic baseball cards of all-time. Not only is it the top rookie card of a generation-defining great, but it also helped kick off a new era in the hobby as card #1 in Upper Deck's debut release. So how does one go about making such an important card better? By getting it signed.
This card includes an aftermarket autograph from the Hall of Famer. Like his swing, the elegant penmanship is classic.
The card itself has been graded a Gem Mint 10 by PSA. The signature also carries a grade of 10.
While nearly 4,250 unsigned copies of the card carry a PSA 10 grade, this is one of just 123 copies to achieve the highest possible dual-grade from the company.
The certification number on this card has been checked against the third-party grader's online database and is active as of 04/17/2026.
