The 2023 Donruss Cooperstown George Brett Blue #CT15 is a Baseball card (Blue parallel) released in 2023. Ungraded copies carry a market value of about $4.99.
An ungraded copy is worth around $4.99, a PSA 9 around $16.14, a PSA 10 (Gem Mint) around $42.08 and a pristine BGS 10 around $55.00. 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?
The spread between raw ($4.99) and top-graded ($42.08) 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.
