The 2023 Finest Base Set Corey Seager Blue Aqua Vapor #21 is a Baseball card (Blue Aqua Vapor parallel) released in 2023. Ungraded copies carry a market value of about $3.31.
An ungraded copy is worth around $3.31, a PSA 9 around $9.00, a PSA 10 (Gem Mint) around $13.50 and a pristine BGS 10 around $18.00. That's roughly a 4.1× 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 ($3.31) and top-graded ($13.50) 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.
