The 2026 Bowman Chrome Prospect Autograph Keyner Martinez #CPA-KMA is a Baseball card released in 2026. Ungraded copies carry a market value of about $4.32.
An ungraded copy is worth around $4.32, a PSA 9 around $19.22, a PSA 10 (Gem Mint) around $57.26 and a pristine BGS 10 around $74.00. That's roughly a 13× premium for a gem-mint copy over raw — one of the clearest signals that condition-sensitive buyers dominate this card's market.
Is it worth grading?
With raw copies near $4.32 and top grades reaching $57.26, grading a sharp copy of this card can clearly pay for itself — the spread comfortably covers a typical ~$25.00 grading fee. The catch: only submit copies with strong centering, clean corners, and unmarked surfaces, because anything below a 9 usually erases the math.
