The 2020-21 Panini Select Base Set Isaiah Stewart Silver Prizm #191 is a Basketball card (Silver Prizm parallel) released in 2021. Ungraded copies carry a market value of about $1.30.
An ungraded copy is worth around $1.30, a PSA 9 around $11.43, a PSA 10 (Gem Mint) around $32.13 and a pristine BGS 10 around $42.00. That's roughly a 25× 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 ($1.30) and top-graded ($32.13) 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.
