2025 Topps Chrome Platinum Base Set George Brett Rose Gold Mini-Diamond Refractor #429 value & prices

The 2025 Topps Chrome Platinum Base Set George Brett Rose Gold Mini-Diamond Refractor #429 is a Baseball card (Rose Gold Mini-Diamond Refractor parallel) released in 2025. Ungraded copies carry a market value of about $18.99.

An ungraded copy is worth around $18.99, a PSA 9 around $28.31, a PSA 10 (Gem Mint) around $82.65 and a pristine BGS 10 around $107.00. That's roughly a 4.4× 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 $18.99 and top grades reaching $82.65, 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.
