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
As a 1989 Fleer issue, this base card occupies a lower tier in the market value hierarchy compared to Keith Hernandez’s rookie cards or high-end parallels. While it serves as an accessible entry point for Mets collectors, it trades significantly below the premiums commanded by graded examples or short-print variants. The card reflects standard market conditions for unremarked base cards from this era, where condition sensitivity heavily dictates relative pricing.
Rarity Breakdown
This card lacks any scarcity mechanics such as serial numbering, short-print designation, or parallel foil treatments, placing it at the most abundant level of the set. It is a standard base card, meaning supply is constrained only by the original print run rather than individualized limits or special production runs. Consequently, it does not benefit from the supply-side dynamics that drive premiums in serial-numbered or one-of-one items.
Investment Outlook
Hernandez’s tenure with the New York Mets provides a solid collector demand driver, though this specific base card lacks the rookie-card premium mechanics that typically drive long-term value appreciation. The absence of special attributes limits its appeal to serious investors seeking rarity, restricting growth potential to general market fluctuations rather than scarcity-driven demand. Collectors may find it useful for completing base sets, but it does not offer the same investment upside as his earlier career issues.
