The 1999 SP Signature Autograph Koy Detmer #KD is a Football card released in 1999. Ungraded copies carry a market value of about $9.50.
An ungraded copy is worth around $9.50, a PSA 10 (Gem Mint) around $54.14 and a pristine BGS 10 around $70.00. That's roughly a 5.7× 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 ($9.50) and top-graded ($54.14) 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.
