The 2025-26 Topps Chrome Activators Kon Knueppel Yellow Refractor #AC-14 is a Basketball card (Yellow Refractor parallel) released in 2025. Ungraded copies carry a market value of about $50.31.
An ungraded copy is worth around $50.31, a PSA 9 around $85.72, a PSA 10 (Gem Mint) around $237.10 and a pristine BGS 10 around $308.00. That's roughly a 4.7× 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 $50.31 and top grades reaching $237.10, 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.
