The 1999 SP Signature Autographs Doug Mientkiewicz #DoM is a Baseball card released in 1999. Ungraded copies carry a market value of about $8.99.
An ungraded copy is worth around $8.99, a PSA 9 around $44.69, a PSA 10 (Gem Mint) around $115.24 and a pristine BGS 10 around $150.00. 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?
With raw copies near $8.99 and top grades reaching $115.24, 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.
