The 2025-26 Topps Big Box Ballers Kon Knueppel #BB-4 is a Basketball card. Ungraded copies carry a market value of about $8.48.
An ungraded copy is worth around $8.48, a PSA 9 around $48.40, a PSA 10 (Gem Mint) around $90.00 and a pristine BGS 10 around $117.00. That's roughly a 11× 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 $8.48 and top grades reaching $90.00, 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.
