The 2021-22 Upper Deck Credentials Main Stage Signatures Klim Kostin #BTS-KK is a Hockey card. Ungraded copies carry a market value of about $3.20.
An ungraded copy is worth around $3.20, a PSA 9 around $13.55, a PSA 10 (Gem Mint) around $35.22 and a pristine BGS 10 around $46.00. That's roughly a 11× 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 ($3.20) and top-graded ($35.22) 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.
