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 Ron Harper card sits at a foundational entry-level tier, reflecting the brand's mass-produced nature during the early 1990s basketball boom. While Harper's tenure with the Los Angeles Clippers establishes his baseline significance, the lack of special attributes keeps this base parallel trading well below his premium rookie or autograph counterparts. The current market positioning suggests it serves primarily as a bulk acquisition for fillers rather than a standalone value holder.
Rarity Breakdown
The card carries no special scarcity mechanics, as it is a standard base issue without serial numbering, short-print status, or parallel variations. This unadorned presentation means supply is effectively unlimited relative to collector demand, as no print run restrictions or one-of-one constraints apply. Consequently, the card relies entirely on general set completion needs rather than inherent rarity to maintain its presence in the market.
Investment Outlook
As a non-rookie base card from a high-volume set, this item lacks the premium mechanics typically associated with strong appreciation potential. Collector demand is likely driven solely by the desire to complete a base set of the 1990-91 Skybox release rather than speculative growth. Investors should view this as a low-risk, low-reward acquisition suitable only for specific set assembly needs.
