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 1989 Pro Set card of John Frank sits at a modest entry-level price point, reflecting his status as a role player rather than a franchise cornerstone for the San Francisco 49ers. While it lacks the premium valuation associated with superstar teammates, it remains accessible for collectors focusing on late-80s NFL history. The single active listing suggests a thin market, meaning any sale could shift the perceived baseline for this specific item.
Rarity Breakdown
As a base card with no special attributes like serial numbering, short printing, or parallels, the supply is determined entirely by the original print run of the 1989 Pro Set set. This means it is a mass-produced item where availability is high, preventing any scarcity-driven value appreciation. Without limited edition mechanics, the card relies on standard distribution channels rather than constrained supply.
Investment Outlook
Investment potential is limited by the lack of rookie card status and the absence of special parallel or insert variations that typically drive collector demand. While it holds nostalgic value for 49ers fans from the late 1980s, it does not possess the key attributes necessary for significant market growth. Collectors are more likely to acquire this for completionist purposes within the broader 1989 Pro Set set rather than as a standalone financial asset.
