The 2021 Topps Chrome NPB Nippon Professional Koki Yamaguchi Blue #112 is a Baseball card (Blue parallel) released in 2021. Ungraded copies carry a market value of about $7.57.
An ungraded copy is worth around $7.57, a PSA 9 around $18.24, a PSA 10 (Gem Mint) around $41.97 and a pristine BGS 10 around $55.00. That's roughly a 5.5× 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 ($7.57) and top-graded ($41.97) 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.
