The 1999 SP Signature Autographs Harmon Killebrew #HK is a Baseball card released in 1999. Ungraded copies carry a market value of about $75.00.
An ungraded copy is worth around $75.00, a PSA 9 around $123.00, a PSA 10 (Gem Mint) around $155.83 and a pristine BGS 10 around $203.00. The gem-mint premium is modest (about 2.1× raw), so condition matters here but doesn't completely define the price.
Is it worth grading?
With raw copies near $75.00 and top grades reaching $155.83, 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.
