The 2021 Donruss Optic Rated Rookies Signatures Ryan Mountcastle Red #RRS-RM is a Baseball card (Red parallel) released in 2021. Ungraded copies carry a market value of about $7.72.
An ungraded copy is worth around $7.72, a PSA 9 around $15.50, a PSA 10 (Gem Mint) around $26.00 and a pristine BGS 10 around $34.00. That's roughly a 3.4× 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 ($7.72) and top-graded ($26.00) 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.
