The 2025 Topps Chrome Platinum Autographs Coby Mayo Green Mini-Diamond #CPA-CMA is a Baseball card (Green Mini-Diamond parallel) released in 2025. Ungraded copies carry a market value of about $22.50.
An ungraded copy is worth around $22.50, a PSA 9 around $49.18, a PSA 10 (Gem Mint) around $142.69 and a pristine BGS 10 around $186.00. That's roughly a 6.3× 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 $22.50 and top grades reaching $142.69, 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.
