The 2021 Panini Mosaic Big Fly Ken Griffey Jr. Green Fluorescent #BF5 is a Baseball card (Green Fluorescent parallel) released in 2021. Ungraded copies carry a market value of about $3.22.
An ungraded copy is worth around $3.22, a PSA 9 around $12.50, a PSA 10 (Gem Mint) around $20.00 and a pristine BGS 10 around $26.00. That's roughly a 6.2× 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 ($3.22) and top-graded ($20.00) 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.
