The 2026 Topps Finest Ketel Marte Black Refractor #4 is a Baseball card (Black Refractor parallel) released in 2026. Ungraded copies carry a market value of about $17.93.
An ungraded copy is worth around $17.93, a PSA 9 around $38.94, a PSA 10 (Gem Mint) around $114.39 and a pristine BGS 10 around $149.00. That's roughly a 6.4× 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 $17.93 and top grades reaching $114.39, 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.
