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 Upper Deck card represents a foundational entry for Roger Clemens, capturing the early stage of his career with the Boston Red Sox before his subsequent stardom. While the base condition generally places it in an accessible price tier, the specific 'Low Number' designation within this set creates a distinct premium over standard issues. The current active listing count suggests a tight supply environment, which supports value retention even if the absolute price point appears modest.
Rarity Breakdown
The primary scarcity driver for this item is its classification as a 'Low Number' card, which inherently limits the available supply compared to the base set. This numerical constraint creates a vertical rarity hierarchy where lower serial numbers are prized by collectors seeking specific identifiers. Without additional parallel or short-print attributes, the value is derived entirely from this serial numbering mechanic rather than unique printing variations.
Investment Outlook
As a rookie-year card from a premier brand like Upper Deck, this item benefits from the structural demand for Clemens' early career memorabilia. The 'Low Number' attribute provides a durable collector demand driver that typically outperforms standard base cards over time. Interest is likely sustained by completists focusing on specific serial number ranges within the 1990 set, ensuring steady liquidity for well-preserved examples.
