The 2025-26 Finest Base Set Stephon Castle Gold Geometric Refractor #100 is a Basketball card (Gold Geometric Refractor parallel) released in 2026. Ungraded copies carry a market value of about $54.85.
An ungraded copy is worth around $54.85, a PSA 10 (Gem Mint) around $319.00 and a pristine BGS 10 around $415.00. That's roughly a 5.8× 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 $54.85 and top grades reaching $319.00, 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.
