The 2021 Donruss Optic Base Set Ryan Mountcastle One Hundred #59 is a Baseball card (One Hundred parallel) released in 2021. Ungraded copies carry a market value of about $3.49.
An ungraded copy is worth around $3.49, a PSA 10 (Gem Mint) around $14.99 and a pristine BGS 10 around $19.00. That's roughly a 4.3× 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 ($3.49) and top-graded ($14.99) 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.
