The 2025-26 Bowman Hobby Stars Kon Knueppel Green Refractor #HS-7 is a Basketball card (Green Refractor parallel) released in 2026. Ungraded copies carry a market value of about $38.50.
An ungraded copy is worth around $38.50, a PSA 9 around $69.72, a PSA 10 (Gem Mint) around $199.67 and a pristine BGS 10 around $260.00. That's roughly a 5.2× 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 $38.50 and top grades reaching $199.67, 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.
