The 2025-26 Finest Base Set Shai Gilgeous-Alexander Oil Spill Refractor #266 is a Basketball card (Oil Spill Refractor parallel) released in 2026. Ungraded copies carry a market value of about $76.60.
An ungraded copy is worth around $76.60, a PSA 9 around $121.38, a PSA 10 (Gem Mint) around $340.96 and a pristine BGS 10 around $443.00. That's roughly a 4.5× 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 $76.60 and top grades reaching $340.96, 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.
