I have two copies of the 1993-94 Topps Stadium Club Michael Jordan Prototype #1 available for sale. One is a BGS 9, the other a BGS 8. Both are labeled correctly as promos, not the common, base issue.
Asking $300 obo on the BGS 9
$150 obo on the BGS 8 (could benefit from re-grade, very nice copy)
Nearly impossible Jordan promo card, never offered for sale and never found in this clean condition.
PM with reasonable offers and any questions you may have.
