The 2024-25 Bowman's Best University Base Set Kon Knueppel Geometric Refractor #48 is a Basketball card (Geometric Refractor parallel) released in 2025. Ungraded copies carry a market value of about $10.00.
An ungraded copy is worth around $10.00, a PSA 9 around $24.38, a PSA 10 (Gem Mint) around $66.94 and a pristine BGS 10 around $87.00. That's roughly a 6.7× 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 $10.00 and top grades reaching $66.94, 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.
