The 2025-26 Finest Base Set Kon Knueppel Oil Spill Refractor #204 is a Basketball card (Oil Spill Refractor parallel) released in 2026. Ungraded copies carry a market value of about $395.79.
An ungraded copy is worth around $395.79, a PSA 9 around $259.00, a PSA 10 (Gem Mint) around $665.00 and a pristine BGS 10 around $865.00. The gem-mint premium is modest (about 1.7× raw), so condition matters here but doesn't completely define the price.
Is it worth grading?
With raw copies near $395.79 and top grades reaching $665.00, 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.
