The 2025-26 Topps Cosmic Chrome Propulsion Kon Knueppel Purple Nebula Refractor #PRP-19 is a Basketball card (Purple Nebula Refractor parallel) released in 2026. Ungraded copies carry a market value of about $75.52.
An ungraded copy is worth around $75.52, a PSA 9 around $128.32, a PSA 10 (Gem Mint) around $367.44 and a pristine BGS 10 around $478.00. That's roughly a 4.9× 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 $75.52 and top grades reaching $367.44, 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.
