The 2025-26 Topps Chrome Generation Rising Kon Knueppel Refractor Purple Geometric #GR-4 is a Basketball card (Refractor Purple Geometric parallel) released in 2025. Ungraded copies carry a market value of about $219.00.
An ungraded copy is worth around $219.00, a PSA 9 around $225.81, a PSA 10 (Gem Mint) around $351.19 and a pristine BGS 10 around $457.00. The gem-mint premium is modest (about 1.6× raw), so condition matters here but doesn't completely define the price.
Is it worth grading?
With raw copies near $219.00 and top grades reaching $351.19, 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.
