The 2023 Bowman Chrome WBC Flag Refractors Kunwoo Park #WBC-18 is a Baseball card released in 2023. Ungraded copies carry a market value of about $3.25.
An ungraded copy is worth around $3.25, a PSA 9 around $14.25, a PSA 10 (Gem Mint) around $38.35 and a pristine BGS 10 around $50.00. That's roughly a 12× 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 ($3.25) and top-graded ($38.35) 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.
