The 2025-26 Finest Base Set Cooper Flagg Gold Geometric Refractor #1 is a Basketball card (Gold Geometric Refractor parallel) released in 2026. Ungraded copies carry a market value of about $566.00.
An ungraded copy is worth around $566.00, a PSA 9 around $875.72, a PSA 10 (Gem Mint) around $2,100.00, a pristine BGS 10 around $2 and730.00. That's roughly a 3.7× 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 $566.00 and top grades reaching $2,100.00, 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.
