The 2025-26 Topps Rise to Stardom Kon Knueppel Green Rainbow #RTS-4 is a Basketball card (Green Rainbow parallel) released in 2025. Ungraded copies carry a market value of about $50.20.
An ungraded copy is worth around $50.20, a PSA 9 around $84.63, a PSA 10 (Gem Mint) around $230.89 and a pristine BGS 10 around $300.00. That's roughly a 4.6× 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 $50.20 and top grades reaching $230.89, 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.
