The 2023 Finest Flashbacks Base Set Matt Wallner #15 is a Baseball card released in 2023. Ungraded copies carry a market value of about $1.56.
An ungraded copy is worth around $1.56, a PSA 9 around $7.00, a PSA 10 (Gem Mint) around $33.78 and a pristine BGS 10 around $44.00. That's roughly a 22× 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 ($1.56) and top-graded ($33.78) 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.
