1998 Upper Deck Black Diamond Charles Barkley Double #40 value & prices

The 1998 Upper Deck Black Diamond Charles Barkley Double #40 is a Basketball card (Double parallel) released in 1998. Ungraded copies carry a market value of about $4.32.

An ungraded copy is worth around $4.32, a PSA 10 (Gem Mint) around $75.00 and a pristine BGS 10 around $98.00. That's roughly a 17× 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 $4.32 and top grades reaching $75.00, 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.
