The 2021 Donruss Optic Fort Knox Mookie Betts #FK6 is a Baseball card released in 2021. Ungraded copies carry a market value of about $25.00.
An ungraded copy is worth around $25.00, a PSA 10 (Gem Mint) around $67.78 and a pristine BGS 10 around $88.00. The gem-mint premium is modest (about 2.7× raw), so condition matters here but doesn't completely define the price.
Is it worth grading?
The spread between raw ($25.00) and top-graded ($67.78) 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.
