The 1999 SP Signature Koy Detmer Autograph #KD is a Football card (Autograph parallel) released in 1999. Ungraded copies carry a market value of about $4.28.
An ungraded copy is worth around $4.28, a PSA 9 around $26.75, a PSA 10 (Gem Mint) around $123.50 and a pristine BGS 10 around $161.00. That's roughly a 29× 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?
With raw copies near $4.28 and top grades reaching $123.50, grading a sharp copy of this card can clearly pay for itself — the spread comfortably covers a typical ~$25.00 grading fee. The catch: only submit copies with strong centering, clean corners, and unmarked surfaces, because anything below a 9 usually erases the math.
