The 2025-26 Topps Chrome Youthquake Kon Knueppel Refractor Red #YQ-4 is a Basketball card (Refractor Red parallel) released in 2025. Ungraded copies carry a market value of about $1,625.00.
An ungraded copy is worth around $1,625.00, a PSA 10 (Gem Mint) around $2,062.00, a pristine BGS 10 around $2 and681.00. The gem-mint premium is modest (about 1.3× raw), so condition matters here but doesn't completely define the price.
Is it worth grading?
With raw copies near $1,625.00 and top grades reaching $2,062.00, 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.
