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 Topps Greg Briley card sits at the lower end of the market value spectrum, reflecting its status as a standard issue from a major brand rather than a premium insert. The current pricing indicates it trades below market for significant players, serving primarily as an affordable entry point for collectors building specific team sets. Its value is largely derived from its completeness within the 1990 Topps base set rather than individual player performance metrics.
Rarity Breakdown
The card possesses no special scarcity attributes, meaning it is a standard base parallel with an open market supply typical of mass-produced inserts from this era. Unlike serial-numbered or short-print variants, this particular slab does not benefit from limited edition mechanics or unique parallel treatments that would constrain availability. Consequently, the supply is effectively unlimited relative to collector demand, keeping its rarity profile at the lowest tier.
Investment Outlook
As a non-rookie card from a standard set, this item lacks the rookie-card premium mechanics that typically drive long-term appreciation in the baseball market. Collector demand is likely limited to those seeking specific set completions rather than speculative investors, resulting in a stable but stagnant outlook. The absence of special parallels or short-print designations means it is unlikely to see significant price appreciation independent of broader set-level trends.
