The 2021 Donruss Optic Base Set Ketel Marte Red #137 is a Baseball card (Red parallel) released in 2021. Ungraded copies carry a market value of about $0.25.
An ungraded copy is worth around $0.25, a PSA 10 (Gem Mint) around $11.65 and a pristine BGS 10 around $15.00. That's roughly a 47× 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 ($0.25) and top-graded ($11.65) 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.
