The 2025-26 Finest Base Set Kon Knueppel Blue Geometric Refractor #104 is a Basketball card (Blue Geometric Refractor parallel) released in 2026. Ungraded copies carry a market value of about $202.50.
An ungraded copy is worth around $202.50, a PSA 9 around $204.00, a PSA 10 (Gem Mint) around $349.50 and a pristine BGS 10 around $454.00. 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 $202.50 and top grades reaching $349.50, 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.
