The 2025-26 Topps Chrome Generation Rising Kon Knueppel Refractor Red Geometric #GR-4 is a Basketball card (Refractor Red Geometric parallel) released in 2025. Ungraded copies carry a market value of about $910.00.
An ungraded copy is worth around $910.00, a PSA 10 (Gem Mint) around $3,500.00, a pristine BGS 10 around $4 and550.00. That's roughly a 3.8× 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 $910.00 and top grades reaching $3,500.00, 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.
