The 2026 Topps Finest Konnor Griffin Blue Mini Diamond Refractor #139 is a Baseball card (Blue Mini Diamond Refractor parallel) released in 2026. Ungraded copies carry a market value of about $39.99.
An ungraded copy is worth around $39.99, a PSA 9 around $78.00, a PSA 10 (Gem Mint) around $228.21 and a pristine BGS 10 around $297.00. That's roughly a 5.7× 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 $39.99 and top grades reaching $228.21, 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.
