The 2025-26 Topps Chrome Ball of Duty Kon Knueppel Blue Refractor #BD-23 is a Basketball card (Blue Refractor parallel) released in 2025. Ungraded copies carry a market value of about $129.51.
An ungraded copy is worth around $129.51, a PSA 9 around $131.00, a PSA 10 (Gem Mint) around $426.94 and a pristine BGS 10 around $555.00. That's roughly a 3.3× 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 $129.51 and top grades reaching $426.94, 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.
