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 card represents a foundational piece of Bert Blyleven's portfolio but sits at the lower end of his market hierarchy due to the brand's positioning in the late-80s landscape. The current pricing indicates a stable, accessible entry point for collectors seeking his Minnesota Twins tenure, reflecting strong demand for his career achievements without the speculative premium seen in higher-tier parallels. Its value is anchored by Blyleven's established legacy rather than short-term market volatility.
Rarity Breakdown
This specific item is a standard base card with no noted serial numbering, short-print designations, or parallel variations, meaning it shares the broadest possible supply within the 1989 Fleer set. The absence of unique scarcity mechanics implies that availability is driven entirely by the original print run and current survivorship rates of ungraded or lightly graded copies. Collectors should expect it to trade in line with other base issues from this era unless condition significantly differentiates it.
Investment Outlook
Investment potential is driven by long-term collector demand for Blyleven's Hall of Fame-caliber statistics rather than intrinsic card rarity, as base cards from this era typically appreciate slowly. The 1989 Fleer set is well-regarded for its design, which supports steady interest from vintage collectors, but the lack of special attributes limits upside compared to graded or parallel examples. Focus on condition quality and population reports for high-grade examples to maximize potential returns.
