Though Ken Griffey Jr.’s 1989 Upper Deck rookie card is by far his most famous card — and among the most iconic in history — it isn’t his most valuable card.
That distinction currently belongs to his 1998 Upper Deck A Piece of the Action 3 card /24, which sold for $84,000 in October 2022.
But that might change soon, as another Griffey card from the same year has a pre-sale estimate of $200,000 at Heritage Auctions.
This example, a 1998 SkyBox E-X 2001 Essential Credentials Now limited to 10 copies, is considered one of Griffey’s best 1990s grails.
The 1998 SkyBox E-X 2001 release had two parallel sets: Essential Credentials Now and Future.
In the Now set, cards are numbered to match numbering in the set — Griffey’s card is No. 10, so it has 10 copies. In the Future set, it is numbered in reverse, starting at 101 and counting down to the card’s place in the set, so Griffey’s Future parallel has 91 copies.
PSA has graded just four copies of the Griffey Now parallel, none of which appear in public sales records.
PSA has graded 30 copies of the more common Griffey Future parallel, with a top sale of $27,300.
In March 2024, Goldin Auctions sold a pair of uncut sheets from the Now parallel set for $16,468.
