The 2021 Bowman Chrome Sapphire Edition Base Set Buster Posey Green #31 is a Baseball card (Green parallel) released in 2021. Ungraded copies carry a market value of about $4.49.
An ungraded copy is worth around $4.49, a PSA 9 around $14.38, a PSA 10 (Gem Mint) around $91.12 and a pristine BGS 10 around $118.00. That's roughly a 20× 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 $4.49 and top grades reaching $91.12, 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.
