Below grade 10 the guide publishes one estimate across all graders, so these rows are not PSA, BGS, CGC or SGC prices, and a low slabbed grade can sit below a clean raw copy. Grade 10 is estimated per grader.
Each point is the last stored observation that day for this printing, condition, grader, autograph status and source. Gaps mean no observation; guide estimates and asking prices are not completed sales.

SuperCatch Expert Analysis
Market Value Insight
This base 1990-91 Fleer card of Mike Gminski represents an entry-level tier within the broader Philadelphia 76ers memorabilia market, trading at a modest premium relative to its raw condition status. While Gminski holds historical significance for the franchise, this particular iteration lacks the scarcity drivers that typically elevate value, keeping it accessible for casual collectors. The pricing reflects its status as a common base card rather than a premium insert or parallel variant.
Rarity Breakdown
As a standard base card without noted special attributes, this item does not carry specific scarcity mechanics such as serial numbering, short-print status, or one-of-one designations. Its supply is determined solely by the standard print run of the 1990-91 Fleer set, meaning it is widely available and unconfined by limited edition constraints. Collectors should view this as a common variant where rarity is dictated by condition rather than intentional production limits.
Investment Outlook
The investment potential for this card is limited due to the absence of rookie-card status, which is the primary driver for long-term value appreciation in basketball collectibles. Demand remains steady among niche collectors seeking specific era representations of the 76ers, but the lack of parallel versions or special attributes restricts upward price momentum. It serves best as a filler piece for a complete set rather than a standalone asset for capital growth.
