The 2025 Topps Museum Collection Base Set Marcelo Mayer Black Diamond #91 is a Baseball card (Black Diamond parallel) released in 2025. Ungraded copies carry a market value of about $21.86.
An ungraded copy is worth around $21.86, a PSA 9 around $43.37, a PSA 10 (Gem Mint) around $122.92 and a pristine BGS 10 around $160.00. That's roughly a 5.6× 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 $21.86 and top grades reaching $122.92, 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.
