The 2026 Panini Donruss Jersey Kings Marcelo Mayer Blue #JK-MM is a Baseball card (Blue parallel) released in 2026. Ungraded copies carry a market value of about $5.49.
An ungraded copy is worth around $5.49, a PSA 9 around $18.59, a PSA 10 (Gem Mint) around $54.66 and a pristine BGS 10 around $71.00. That's roughly a 10.0× 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 ($5.49) and top-graded ($54.66) 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.
