The 2025 Donruss Signature Series Ken O'Brien Blue #SS-KON is a Football card (Blue parallel) released in 2025. Ungraded copies carry a market value of about $3.45.
An ungraded copy is worth around $3.45, a PSA 9 around $15.09, a PSA 10 (Gem Mint) around $43.57 and a pristine BGS 10 around $57.00. That's roughly a 13× 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 ($3.45) and top-graded ($43.57) 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.
