The 2020-21 O-Pee-Chee Platinum Base Set Nathan MacKinnon Aquamarine #4 is a Hockey card (Aquamarine parallel) released in 2020. Ungraded copies carry a market value of about $3.92.
An ungraded copy is worth around $3.92, a PSA 9 around $9.50, a PSA 10 (Gem Mint) around $35.21 and a pristine BGS 10 around $46.00. That's roughly a 9.0× 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 ($3.92) and top-graded ($35.21) 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.
