The 2021 Finest Base Set Ryan Mountcastle Aqua Shimmer Refractor #2 is a Baseball card (Aqua Shimmer Refractor parallel) released in 2021. Ungraded copies carry a market value of about $6.64.
An ungraded copy is worth around $6.64, a PSA 10 (Gem Mint) around $27.04 and a pristine BGS 10 around $35.00. That's roughly a 4.1× 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 ($6.64) and top-graded ($27.04) 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.
