The 2025-26 Topps Flagship Real One Relics Kon Knueppel #FRO-KK is a Basketball card. Ungraded copies carry a market value of about $20.50.
An ungraded copy is worth around $20.50, a PSA 9 around $250.00, a PSA 10 (Gem Mint) around $300.00 and a pristine BGS 10 around $390.00. That's roughly a 15× 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 $20.50 and top grades reaching $300.00, 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.
