The 2024-25 Bowman's Best University Base Set Kon Knueppel Gold Geometric Refractor #48 is a Basketball card (Gold Geometric Refractor parallel) released in 2025. Ungraded copies carry a market value of about $29.88.
An ungraded copy is worth around $29.88, a PSA 9 around $52.94, a PSA 10 (Gem Mint) around $140.28 and a pristine BGS 10 around $182.00. That's roughly a 4.7× 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 $29.88 and top grades reaching $140.28, 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.
