The 2025-26 Finest First Kon Knueppel Geometric Refractor #F-4 is a Basketball card (Geometric Refractor parallel) released in 2026. Ungraded copies carry a market value of about $35.00.
An ungraded copy is worth around $35.00, a PSA 9 around $60.00, a PSA 10 (Gem Mint) around $162.45 and a pristine BGS 10 around $211.00. That's roughly a 4.6× 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 $35.00 and top grades reaching $162.45, 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.
