The 2021 Bowman Chrome Prospect Autographs Sean Roby Purple Refractor #CPA-SRO is a Baseball card (Purple Refractor parallel) released in 2021. Ungraded copies carry a market value of about $2.99.
An ungraded copy is worth around $2.99, a PSA 10 (Gem Mint) around $21.90 and a pristine BGS 10 around $28.00. That's roughly a 7.3× 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 ($2.99) and top-graded ($21.90) 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.
