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 card represents a baseline entry point for Greg Jelks collectors, reflecting its status as a standard issue from the 1988 Fleer set rather than a premium parallel or insert. As a non-rookie card for a player with limited MLB tenure, it trades at a modest tier relative to more significant career milestones or higher-grade examples. The current pricing suggests a stable, accessible market position typical for common base cards of this era and player profile.
Rarity Breakdown
The card carries no special scarcity attributes such as serial numbering, short-print designation, or unique parallels, meaning its supply is determined solely by the original base print run. It exists as a common base card within the 1988 Fleer baseball set, lacking any mechanical constraints on availability that would differentiate it from other copies in the same set. This uniformity in production ensures that the supply remains abundant relative to specialized variants.
Investment Outlook
As a non-rookie card, this item does not benefit from the rookie-card premium mechanics that typically drive long-term value appreciation for players with sustained careers. Collector demand is likely driven by set completionists seeking to fill gaps in their 1988 Fleer collections rather than speculative interest in the player's future performance. The outlook remains stable but modest, relying on steady demand for vintage baseball staples rather than growth potential.
