The 2020-21 Donruss Optic Base Set Isaiah Stewart Gold #166 is a Basketball card (Gold parallel) released in 2021. Ungraded copies carry a market value of about $138.11.
An ungraded copy is worth around $138.11, a PSA 9 around $250.00, a PSA 10 (Gem Mint) around $410.86 and a pristine BGS 10 around $534.00. The gem-mint premium is modest (about 3.0× raw), so condition matters here but doesn't completely define the price.
Is it worth grading?
With raw copies near $138.11 and top grades reaching $410.86, 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.
