The 2021 Donruss Optic Rated Rookies Signatures Ryan Mountcastle White Mojo #RRS-RM is a Baseball card (White Mojo parallel) released in 2021. Ungraded copies carry a market value of about $6.51.
An ungraded copy is worth around $6.51, a PSA 9 around $26.00, a PSA 10 (Gem Mint) around $99.99 and a pristine BGS 10 around $130.00. That's roughly a 15× 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?
With raw copies near $6.51 and top grades reaching $99.99, grading a sharp copy of this card can clearly pay for itself — the spread comfortably covers a typical ~$25.00 grading fee. The catch: only submit copies with strong centering, clean corners, and unmarked surfaces, because anything below a 9 usually erases the math.
