The 2021 Topps Chrome Platinum Anniversary Base Set Roger Clemens Platinum 70th Anniversary Mini Diamond Refractor #603 is a Baseball card (Platinum 70th Anniversary Mini Diamond Refractor parallel) released in 2021. Ungraded copies carry a market value of about $12.80.
An ungraded copy is worth around $12.80, a PSA 10 (Gem Mint) around $81.00 and a pristine BGS 10 around $105.00. That's roughly a 6.3× 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 $12.80 and top grades reaching $81.00, 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.
