The 2018 Bowman Chrome Prospects Autographs Jose Siri Purple Refractor #CPA-JS is a Baseball card (Purple Refractor parallel) released in 2018. Ungraded copies carry a market value of about $4.25.
An ungraded copy is worth around $4.25, a PSA 9 around $35.00, a PSA 10 (Gem Mint) around $50.00 and a pristine BGS 10 around $65.00. That's roughly a 12× 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 ($4.25) and top-graded ($50.00) 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.
