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
The 1989 Bowman Pete Harnisch card occupies the lower tier of his collectible footprint, typical of base rookie-era cards from this set which was known for its oversized format and wide print run. Harnisch's career as a solid mid-rotation starter rather than an elite ace limits the premium this card commands relative to contemporaries from the same set. With only one active listing in the current market, price discovery is limited and the card trades at modest levels consistent with late-80s Bowman commons.
Rarity Breakdown
The 1989 Bowman set was produced in substantial quantities, making this a base card with no serial numbering, short print designation, or parallel variant — placing it firmly in the high-supply, low-scarcity category. Graded population reports reflect minimal PSA and BGS submissions for this card, as collector demand for professional grading has historically been low given the set's wide availability. Raw copies far outnumber graded examples, meaning a high-grade PSA 10 or BGS 9.5 could stand out significantly within a thin graded population.
Investment Outlook
Harnisch had a respectable MLB career spanning over a decade but never reached Hall of Fame consideration, which caps the long-term upside for his key cards. The 1989 Bowman set does carry some collector nostalgia appeal, and condition-sensitive buyers occasionally pursue high-grade examples of overlooked players from this era. Grading submission trends for this card remain low, so a pristine raw copy submitted today could achieve a meaningful population report position, though broader market momentum for this subject remains subdued.
