The 2025-26 Finest Base Set James Harden Oil Spill Refractor #278 is a Basketball card (Oil Spill Refractor parallel) released in 2026. Ungraded copies carry a market value of about $28.18.
An ungraded copy is worth around $28.18, a PSA 9 around $53.10, a PSA 10 (Gem Mint) around $150.34 and a pristine BGS 10 around $195.00. That's roughly a 5.3× 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 $28.18 and top grades reaching $150.34, 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.
