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 1989-90 Fleer card represents a foundational entry for Derek Harper, reflecting his established status as a key contributor for the Dallas Mavericks during that era. As a base card from a widely produced set, it occupies the lower tier of the market, trading significantly below premium parallels or specialty inserts. The current valuation aligns with standard production levels for non-premium rookie-adjacent cards from this specific vintage.
Rarity Breakdown
The card lacks any scarcity mechanisms such as serial numbering, short-print status, or limited edition designations, meaning it is part of the unrestricted base set. This unlimited supply relative to parallel versions ensures that availability remains high across the secondary market. Consequently, the card does not carry the exclusivity premiums associated with numbered or refractor variants.
Investment Outlook
While not a rookie card, this issue holds historical value as Harper was in his prime during this season, driving demand from collectors focusing on his specific team tenure. The card's accessibility makes it a suitable component for building complete set collections rather than a standalone speculative asset. Long-term value appreciation is likely to remain modest unless broader interest in 1990s Mavericks history increases.
