The 2021 Panini Mosaic Base Set Kenneth Gainwell Green Mosaic #339 is a Football card (Green Mosaic parallel) released in 2021. Ungraded copies carry a market value of about $1.21.
An ungraded copy is worth around $1.21, a PSA 9 around $7.50, a PSA 10 (Gem Mint) around $13.22 and a pristine BGS 10 around $17.00. That's roughly a 11× 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 ($1.21) and top-graded ($13.22) 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.
