The 2025-26 Topps Chrome Rock Stars Kon Knueppel #RS-19 is a Basketball card. Ungraded copies carry a market value of about $203.75.
An ungraded copy is worth around $203.75, a PSA 9 around $250.00, a PSA 10 (Gem Mint) around $358.83 and a pristine BGS 10 around $466.00. The gem-mint premium is modest (about 1.8× raw), so condition matters here but doesn't completely define the price.
Is it worth grading?
With raw copies near $203.75 and top grades reaching $358.83, 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.
