The 2020 Bowman Chrome Prospects Autograph Seth Gray Purple Refractor #CPA-SG is a Baseball card (Purple Refractor parallel) released in 2020. Ungraded copies carry a market value of about $5.80.
An ungraded copy is worth around $5.80, a PSA 10 (Gem Mint) around $9.67 and a pristine BGS 10 around $13.00. The gem-mint premium is modest (about 1.7× raw), so condition matters here but doesn't completely define the price.
Is it worth grading?
The spread between raw ($5.80) and top-graded ($9.67) 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.
