The 2025-26 Topps Cosmic Chrome Base Set Stephon Castle Blue Moon Refractor #30 is a Basketball card (Blue Moon Refractor parallel) released in 2026. Ungraded copies carry a market value of about $45.00.
An ungraded copy is worth around $45.00, a PSA 9 around $80.01, a PSA 10 (Gem Mint) around $229.56 and a pristine BGS 10 around $298.00. That's roughly a 5.1× 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 $45.00 and top grades reaching $229.56, 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.
