1991 Upper Deck 1991 Upper Deck Baseball Low Series
The Jordan SP1 box, plus Griffey Sr. and Jr. #572
Why it matters
The 1991 Upper Deck Baseball Low Series wax box is the Jordan SP1 box. Upper Deck's second baseball year hid a Michael Jordan card, #SP1, as a short-print insert showing him at a batting cage three years before he walked away from the Bulls to attempt professional baseball. The card is one of the most-hunted non-basketball Jordan cards ever produced. It traded above $500 raw at peak and still holds a hobby-legend premium as the moment Upper Deck accidentally predicted the strangest career pivot in modern sports. The same box also carries Ken Griffey Sr. and Ken Griffey Jr. #572 in the base set, the father-son Mariners card that turned a routine outfield combination into a JW50-canonical artifact. Sealed BBCE-authenticated boxes trade $150 to $300 depending on shrink quality and pack seals.
How to identify
1991 Upper Deck Baseball Low Series wax box, 36 packs of 15 cards each. Wax wrapper is white with the Upper Deck logo and the anti-counterfeit hologram authentication mark on the back of every card inside. BBCE authentication is the standard for sealed. Confirm Low Series (cards #1 to 700) by the checklist header rather than High Series or Final Edition, which shipped as a separate product later in the year. Jordan SP1 is a short print pulled at long odds; possibility is the point, not the odds.
