The 2019 Topps Chrome Sapphire Rookie Autographs Mitch Keller Green Refractor #MKE is a Baseball card (Green Refractor parallel) released in 2019. Ungraded copies carry a market value of about $33.50.
An ungraded copy is worth around $33.50, a PSA 9 around $50.00, a PSA 10 (Gem Mint) around $79.75 and a pristine BGS 10 around $104.00. The gem-mint premium is modest (about 2.4× raw), so condition matters here but doesn't completely define the price.
Is it worth grading?
The spread between raw ($33.50) and top-graded ($79.75) 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.
