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
Ken Brett's 1980 Topps card occupies the lower tier of his overall cardography, as late-career base issues from veterans without significant statistical milestones rarely command premiums over earlier releases. With only one active listing currently available, the market is essentially illiquid, meaning any transaction price is an outlier rather than a reliable benchmark. Brett's career significance as a utility pitcher and older brother of Hall of Famer George Brett adds a modest collector curiosity premium, but this card trades at or near base set pricing.
Rarity Breakdown
As a standard 1980 Topps base card, this issue carries no serial numbering, no parallel distinction, and was printed in the high volumes typical of the Topps mass-production era. Population reports for graded copies are minimal, reflecting low submission interest rather than genuine scarcity — raw copies far outnumber slabbed examples. There are no short print variations or insert designations associated with this card, placing it firmly in the common tier of the set.
Investment Outlook
Brett passed away in 2003, and while deceased players can sometimes see renewed collector interest, the sustained demand here is driven primarily by George Brett completionists and vintage Topps set builders rather than speculative investors. Grading submission trends for this card are essentially flat, with little evidence of population growth that would suggest emerging market momentum. The investment case is narrow and niche — best suited for a themed collection rather than a growth-oriented portfolio.
