The 2020 Bowman Chrome Prospects Autograph Jhon Diaz Purple Refractor #CPA-JDI is a Baseball card (Purple Refractor parallel) released in 2020. Ungraded copies carry a market value of about $9.45.
An ungraded copy is worth around $9.45, a PSA 9 around $66.00, a PSA 10 (Gem Mint) around $79.00 and a pristine BGS 10 around $103.00. That's roughly a 8.4× 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 $9.45 and top grades reaching $79.00, 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.
