The 2023 Bowman's Best University Mario Williams Green Mini Diamond #51 is a Football card (Green Mini Diamond parallel) released in 2023. Ungraded copies carry a market value of about $3.13.
An ungraded copy is worth around $3.13, a PSA 10 (Gem Mint) around $660.00 and a pristine BGS 10 around $858.00. That's roughly a 211× 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 $3.13 and top grades reaching $660.00, 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.
