The 2025-26 Topps Chrome Cactus Jack Base Set Jalen Brunson Purple Mini-Diamond Refractor #4 is a Basketball card (Purple Mini-Diamond Refractor parallel) released in 2026. Ungraded copies carry a market value of about $54.40.
An ungraded copy is worth around $54.40, a PSA 9 around $83.54, a PSA 10 (Gem Mint) around $242.46 and a pristine BGS 10 around $315.00. That's roughly a 4.5× 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 $54.40 and top grades reaching $242.46, 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.
