The 2003 SP Authentic Signatures Kevin Garnett #KG-A is a Basketball card released in 2003. Ungraded copies carry a market value of about $275.00.
An ungraded copy is worth around $275.00, a PSA 9 around $345.14, a PSA 10 (Gem Mint) around $728.00 and a pristine BGS 10 around $946.00. The gem-mint premium is modest (about 2.6× raw), so condition matters here but doesn't completely define the price.
Is it worth grading?
With raw copies near $275.00 and top grades reaching $728.00, 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.
