The 2021 Bowman Chrome Prospect Autographs Shalin Polanco Gold Shimmer Refractor #CPA-SP is a Baseball card (Gold Shimmer Refractor parallel) released in 2021. Ungraded copies carry a market value of about $3.50.
An ungraded copy is worth around $3.50, a PSA 9 around $14.01, a PSA 10 (Gem Mint) around $26.19 and a pristine BGS 10 around $34.00. That's roughly a 7.5× 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 ($3.50) and top-graded ($26.19) 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.
