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 Bowman George Brett sits at the lower end of his overall card market, typical for a late-career base issue from a set that was widely distributed and heavily collected at the time. Brett's Hall of Fame status does provide a floor of collector demand, but this card competes with far more iconic issues from his peak years in the late 1970s and early 1980s that command significantly stronger premiums. Within the 1989 Bowman set itself, this card trades in line with other veteran stars rather than standing out as a key card.
Rarity Breakdown
The 1989 Bowman base set was produced in large quantities, and this Brett card carries no serial numbering, parallel distinction, or insert designation — it is a standard base card with a high print run. Graded population data reflects this accessibility, with numerous PSA and BGS submissions existing across all grades, meaning high-grade copies do not benefit from scarcity-driven premiums. The lack of any short-print or variation status further limits its rarity profile within the hobby.
Investment Outlook
Brett's 1999 Hall of Fame induction and his iconic .390 batting average season in 1980 sustain long-term collector interest, but late-career base cards from mass-produced late-80s sets rarely see meaningful appreciation. Grading submission trends for this card are minimal relative to his key vintage issues, suggesting the collector community prioritizes earlier Topps and O-Pee-Chee releases for investment purposes. This card is better suited as a low-cost addition to a Brett player collection than as a growth-oriented investment.
