The 2020-21 Donruss Optic Base Set Michael Porter Jr. Premium Box Set #75 is a Basketball card (Premium Box Set parallel) released in 2021. Ungraded copies carry a market value of about $3.13.
An ungraded copy is worth around $3.13, a PSA 10 (Gem Mint) around $10.00 and a pristine BGS 10 around $13.00. That's roughly a 3.2× 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 ($3.13) and top-graded ($10.00) 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.
