The 2025-26 Topps Cosmic Chrome Base Set Stephon Castle Gold Interstellar Refractor #30 is a Basketball card (Gold Interstellar Refractor parallel) released in 2026. Ungraded copies carry a market value of about $87.75.
An ungraded copy is worth around $87.75, a PSA 9 around $146.22, a PSA 10 (Gem Mint) around $350.00 and a pristine BGS 10 around $455.00. That's roughly a 4.0× 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 $87.75 and top grades reaching $350.00, 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.
