The 2026 Topps Chrome Black Base Set Brandon Sproat Purple Mini-Diamond Refractor #74 is a Baseball card (Purple Mini-Diamond Refractor parallel) released in 2026. Ungraded copies carry a market value of about $3.25.
An ungraded copy is worth around $3.25, a PSA 9 around $15.05, a PSA 10 (Gem Mint) around $44.38 and a pristine BGS 10 around $58.00. That's roughly a 14× 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?
The spread between raw ($3.25) and top-graded ($44.38) copies is fairly tight, so grading this card only makes financial sense for truly flawless copies — or for collectors who simply prefer slabbed cards for protection and display.
