The 2021 Panini Mosaic Base Set Ke'Bryan Hayes Reactive Blue Mosaic #242 is a Baseball card (Reactive Blue Mosaic parallel) released in 2021. Ungraded copies carry a market value of about $1.72.
An ungraded copy is worth around $1.72, a PSA 9 around $11.91, a PSA 10 (Gem Mint) around $32.93 and a pristine BGS 10 around $43.00. That's roughly a 19× 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 ($1.72) and top-graded ($32.93) 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.
