The 2019 Bowman 30th Anniversary Carter Kieboom Green Refractor #B30-CK is a Baseball card (Green Refractor parallel) released in 2019. Ungraded copies carry a market value of about $2.99.
An ungraded copy is worth around $2.99, a PSA 10 (Gem Mint) around $19.99 and a pristine BGS 10 around $26.00. That's roughly a 6.7× 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 ($2.99) and top-graded ($19.99) 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.
