The 2020-21 O-Pee-Chee Platinum Base Set Mitch Marner Aquamarine #144 is a Hockey card (Aquamarine parallel) released in 2020. Ungraded copies carry a market value of about $3.21.
An ungraded copy is worth around $3.21, a PSA 9 around $13.35, a PSA 10 (Gem Mint) around $34.27 and a pristine BGS 10 around $45.00. That's roughly a 11× 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 ($3.21) and top-graded ($34.27) 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.
