The 2025-26 Topps Chrome Youthquake Kon Knueppel Refractor Purple Geometric #YQ-4 is a Basketball card (Refractor Purple Geometric parallel) released in 2025. Ungraded copies carry a market value of about $96.00.
An ungraded copy is worth around $96.00, a PSA 9 around $143.50, a PSA 10 (Gem Mint) around $329.68 and a pristine BGS 10 around $429.00. That's roughly a 3.4× 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 $96.00 and top grades reaching $329.68, 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.
