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.
History is building. At least two days of matching observations are needed to show a trend.
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 checklist card occupies a distinct niche within the Skybox 1990-91 basketball set, catering specifically to completists rather than star-chasers. Its value is driven by the functional necessity of completing the base set, resulting in a stable but modest price tier compared to individual player inserts. With only one active listing available, the immediate market reflects low liquidity, indicating that interested buyers must act quickly to secure this specific component.
Rarity Breakdown
The card lacks specific scarcity mechanics such as serial numbering, short-print status, or parallel variations, positioning it as a standard base checklist item. Its scarcity is derived purely from the aggregate supply of the entire set rather than individual production limits. This absence of unique attributes means its rarity is uniform across all copies, relying on the total number of sets produced to determine overall availability.
Investment Outlook
Investment potential is tied to the broader demand for completing the 1990-91 Skybox basketball base set, which holds historical significance in the hobby. Collector demand is likely steady among set builders, providing a floor for value, though upside is limited by the lack of player-specific appeal. The card serves as a foundational piece for collectors prioritizing set completion over individual player speculation.
