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
As a base card from the 1990 Skybox set, this item trades at the lower end of the price spectrum, reflecting its status as a common iteration of a player who saw significant tenure with the Cleveland Cavaliers. The lack of special attributes or parallels means it does not command a premium over the broader set, making it an accessible entry point rather than a high-value asset. Its value is primarily driven by the nostalgic appeal of the early 90s era rather than individual player performance metrics or card scarcity.
Rarity Breakdown
This card is a standard base release within the 1990-91 Skybox basketball product, meaning it lacks the supply constraints associated with serial numbering, short prints, or parallel variations. The absence of unique identifiers or limited edition markers indicates that the population of this specific card is relatively high compared to its special counterparts. Consequently, the scarcity mechanics are minimal, relying solely on the general supply of the base set rather than any exclusive distribution factors.
Investment Outlook
While the 1990-91 Skybox set holds historical significance in basketball card collecting, this specific base iteration offers limited appreciation potential due to its common status. The absence of rookie-card mechanics or high-end parallels suggests that demand will remain stable but modest, appealing mainly to completists rather than speculators. Long-term value will likely track with the general interest in early 90s NBA memorabilia rather than individual player accolades, given the card's straightforward classification.
