The 2025 Topps Chrome Platinum Base Set Lefty Grove Diamond Etch Refractor #342 is a Baseball card (Diamond Etch Refractor parallel) released in 2025. Ungraded copies carry a market value of about $23.34.
An ungraded copy is worth around $23.34, a PSA 9 around $46.63, a PSA 10 (Gem Mint) around $135.57 and a pristine BGS 10 around $176.00. That's roughly a 5.8× 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 $23.34 and top grades reaching $135.57, 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.
