The 2025 Topps Chrome Platinum Base Set Greg Maddux Diamond Etch Refractor #303 is a Baseball card (Diamond Etch Refractor parallel) released in 2025. Ungraded copies carry a market value of about $25.00.
An ungraded copy is worth around $25.00, a PSA 9 around $49.25, a PSA 10 (Gem Mint) around $143.13 and a pristine BGS 10 around $186.00. 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 $25.00 and top grades reaching $143.13, 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.
