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 1990-91 Skybox Derek Harper card represents a foundational entry point for collectors targeting Mavericks history, currently trading at a modest price tier relative to high-end rookie or autograph variations. The lack of special attributes suggests it sits near the baseline value for this specific set, offering affordability for those building broad NBA or team-specific collections. Its current market positioning reflects the general accessibility of mid-tier 1990s basketball cards for players who, while significant, do not command the extreme premiums of generational superstars.
Rarity Breakdown
As a standard base card within the 1990-91 Skybox set, this item carries no serial numbering, short-print designations, or parallel finishes that would artificially constrain supply. The scarcity is driven purely by the volume of the original print run for a mainstream basketball product, meaning available copies are relatively abundant compared to insert or chase cards. Without specific grading or limited-edition markers, the supply mechanics reflect the standard distribution model of early 90s mass-market sports cards.
Investment Outlook
The investment potential is rooted in the nostalgic appeal of the early 1990s Skybox brand and Harper's role as a key figure during the Mavericks' formative years. While it lacks the rookie-card premium mechanics or specialized parallel status that typically drive aggressive appreciation, it serves as a stable, low-cost component for diversified sets. Collector demand is likely steady among niche Mavericks historians rather than speculative traders, making it a hold for completeness rather than a high-growth asset.
