The 1999 SP Signature Autograph Robert Porcher #RP 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 9 around $10.63, a PSA 10 (Gem Mint) around $66.91 and a pristine BGS 10 around $87.00. That's roughly a 7.0× 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 $9.50 and top grades reaching $66.91, 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.
