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 Fleer base card represents a low-tier entry point for Derek Harper collectors, trading well below the premium commanded by his rookie issues or high-grade parallels. As a standard base card from the early 90s, it lacks the condition sensitivity and scarcity that drive higher valuations in the broader Fleer set. Consequently, it serves primarily as a functional component for bulk sets rather than a standalone value holder.
Rarity Breakdown
The card possesses no special scarcity attributes, meaning it is a standard base issue with no serial numbering, short-print designation, or parallel variation. This lack of distinct physical differentiators results in a high overall supply within the secondary market, as no limiting mechanics were applied to this specific print. Collectors seeking unique scarcity will find this item indistinguishable from the thousands of other identical copies in circulation.
Investment Outlook
As a non-rookie base card, this item does not benefit from the rookie-card premium mechanics that typically drive long-term appreciation in basketball collectibles. The absence of special parallels or serial numbers limits its appeal to high-end investors, restricting demand to casual collectors filling specific holes in early-90s binders. Without unique scarcity drivers, the card is unlikely to outperform the general market trends for common base cards from this era.
