The 2019 Topps Gallery Base Set Jon Duplantier Artist Proof #21 is a Baseball card (Artist Proof parallel) released in 2019. Ungraded copies carry a market value of about $0.45.
An ungraded copy is worth around $0.45, a PSA 10 (Gem Mint) around $9.29 and a pristine BGS 10 around $12.00. That's roughly a 21× 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 ($0.45) and top-graded ($9.29) 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.
