The 2026 Topps Chrome Black Base Set Pete Alonso Red Mini-Diamond Refractor #18 is a Baseball card (Red Mini-Diamond Refractor parallel) released in 2026. Ungraded copies carry a market value of about $63.75.
An ungraded copy is worth around $63.75, a PSA 9 around $109.10, a PSA 10 (Gem Mint) around $312.22 and a pristine BGS 10 around $406.00. That's roughly a 4.9× 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 $63.75 and top grades reaching $312.22, 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.
