The 2025-26 Bowman Rockstar Rookies Kon Knueppel #RR-4 is a Basketball card. Ungraded copies carry a market value of about $1.93.
An ungraded copy is worth around $1.93, a PSA 9 around $13.14, a PSA 10 (Gem Mint) around $39.08 and a pristine BGS 10 around $51.00. That's roughly a 20× 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 ($1.93) and top-graded ($39.08) 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.
