The 2020-21 Panini Prizm Rookie Signatures Isaac Okoro Black Prizm #RS-IOK is a Basketball card (Black Prizm parallel) released in 2021. Ungraded copies carry a market value of about $6.51.
An ungraded copy is worth around $6.51, a PSA 9 around $17.01, a PSA 10 (Gem Mint) around $19.27 and a pristine BGS 10 around $25.00. 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?
The spread between raw ($6.51) and top-graded ($19.27) 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.
