The 2025-26 Finest Base Set Koby Brea Purple Refractor #131 is a Basketball card (Purple Refractor parallel) released in 2026. Ungraded copies carry a market value of about $2.89.
An ungraded copy is worth around $2.89, a PSA 9 around $11.50, a PSA 10 (Gem Mint) around $42.40 and a pristine BGS 10 around $55.00. That's roughly a 15× 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 ($2.89) and top-graded ($42.40) 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.
