The 2018 Donruss Optic Base Set Mike Trout Post Swing Aqua #121 is a Baseball card (Post Swing Aqua parallel) released in 2018. Ungraded copies carry a market value of about $3.44.
An ungraded copy is worth around $3.44, a PSA 9 around $7.50, a PSA 10 (Gem Mint) around $14.50 and a pristine BGS 10 around $19.00. That's roughly a 4.2× 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 ($3.44) and top-graded ($14.50) 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.
