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 Patrick Ewing card represents a foundational entry point for Knicks collectors, reflecting the player's immediate impact upon entering the league. While it commands a modest value compared to his later marquee issues, it serves as a critical benchmark for the era's basketball card market. The current listing availability suggests a stable, low-volume market where patience often yields better acquisition opportunities than chasing immediate inventory.
Rarity Breakdown
As a standard base card from the 1990-91 Skybox set, this issue does not carry serial numbering, short-print status, or parallel variations that would artificially constrain supply. Its scarcity is driven primarily by condition availability and the natural attrition of cards from nearly three decades ago. Unlike premium inserts, its supply is determined by the original print run, making it a common component in bulk collections rather than a scarce variant.
Investment Outlook
Investment potential here is tied to the long-term demand for Ewing's iconic Knicks tenure rather than speculative rookie premiums. As a widely recognized figure in NBA history, this base card benefits from steady, broad-based collector interest in classic 90s basketball. It is best suited for portfolio diversification within vintage sports sets rather than high-growth speculation, offering exposure to a legacy player without the volatility of graded rarity.
