The 2026 Topps Finest Josh Naylor Green Mini Diamond Refractor #78 is a Baseball card (Green Mini Diamond Refractor parallel) released in 2026. Ungraded copies carry a market value of about $7.95.
An ungraded copy is worth around $7.95, a PSA 9 around $22.60, a PSA 10 (Gem Mint) around $66.70 and a pristine BGS 10 around $87.00. That's roughly a 8.4× 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 $7.95 and top grades reaching $66.70, 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.
