The 2023 Topps Chrome Platinum Anniversary Base Set Corey Seager Blue Mini-Diamond Refractor #308 is a Baseball card (Blue Mini-Diamond Refractor parallel) released in 2023. Ungraded copies carry a market value of about $3.25.
An ungraded copy is worth around $3.25, a PSA 9 around $14.30, a PSA 10 (Gem Mint) around $29.99 and a pristine BGS 10 around $39.00. That's roughly a 9.2× 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 ($3.25) and top-graded ($29.99) 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.
