The 2025 Donruss Jersey Kings Marcelo Mayer #JK-MM is a Baseball card released in 2025. Ungraded copies carry a market value of about $2.08.
An ungraded copy is worth around $2.08, a PSA 9 around $12.96, a PSA 10 (Gem Mint) around $37.68 and a pristine BGS 10 around $49.00. That's roughly a 18× 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 ($2.08) and top-graded ($37.68) 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.
