The 2016 Finest Base Set Ketel Marte Green Refractor #27 is a Baseball card (Green Refractor parallel) released in 2016. Ungraded copies carry a market value of about $1.59.
An ungraded copy is worth around $1.59, a PSA 9 around $19.99, a PSA 10 (Gem Mint) around $32.25 and a pristine BGS 10 around $42.00. That's roughly a 20× 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 ($1.59) and top-graded ($32.25) 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.
