The 1999 Upper Deck Black Diamond A Piece of History Kevin Garnett #KG is a Basketball card released in 1999. Ungraded copies carry a market value of about $19.00.
An ungraded copy is worth around $19.00, a PSA 9 around $66.65, a PSA 10 (Gem Mint) around $346.29 and a pristine BGS 10 around $450.00. That's roughly a 18× 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 $19.00 and top grades reaching $346.29, 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.
