The 2025-26 Topps Signature Class Star Cast Cooper Flagg #SC-21 is a Basketball card. Ungraded copies carry a market value of about $150.00.
An ungraded copy is worth around $150.00, a PSA 9 around $245.05, a PSA 10 (Gem Mint) around $705.86 and a pristine BGS 10 around $918.00. That's roughly a 4.7× 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 $150.00 and top grades reaching $705.86, 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.
