The 1999 Upper Deck Black Diamond Patrick Ewing Diamond Cut #55 is a Basketball card (Diamond Cut parallel) released in 1999. Ungraded copies carry a market value of about $2.54.
An ungraded copy is worth around $2.54, a PSA 9 around $21.51, a PSA 10 (Gem Mint) around $94.23 and a pristine BGS 10 around $123.00. That's roughly a 37× 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 $2.54 and top grades reaching $94.23, 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.
