The 2020-21 Donruss Optic Signature Series Isaiah Stewart Holo #SS-IST is a Basketball card (Holo parallel) released in 2020. Ungraded copies carry a market value of about $6.36.
An ungraded copy is worth around $6.36, a PSA 9 around $16.77, a PSA 10 (Gem Mint) around $38.65 and a pristine BGS 10 around $50.00. That's roughly a 6.1× 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?
The spread between raw ($6.36) and top-graded ($38.65) copies is fairly tight, so grading this card only makes financial sense for truly flawless copies — or for collectors who simply prefer slabbed cards for protection and display.
