The 2017 Finest Base Set Clayton Kershaw Blue Refractor #50 is a Baseball card (Blue Refractor parallel) released in 2017. Ungraded copies carry a market value of about $6.40.
An ungraded copy is worth around $6.40, a PSA 9 around $21.50, a PSA 10 (Gem Mint) around $45.00 and a pristine BGS 10 around $59.00. That's roughly a 7.0× 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 ($6.40) and top-graded ($45.00) 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.
