The 2020-21 O-Pee-Chee Platinum Base Set Mark Stone Aquamarine #40 is a Hockey card (Aquamarine parallel) released in 2020. Ungraded copies carry a market value of about $1.35.
An ungraded copy is worth around $1.35, a PSA 10 (Gem Mint) around $124.99 and a pristine BGS 10 around $162.00. That's roughly a 93× 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?
With raw copies near $1.35 and top grades reaching $124.99, grading a sharp copy of this card can clearly pay for itself — the spread comfortably covers a typical ~$25.00 grading fee. The catch: only submit copies with strong centering, clean corners, and unmarked surfaces, because anything below a 9 usually erases the math.
