The 1984 Star Sly Williams #87 is a Basketball card released in 1984. Ungraded copies carry a market value of about $6.20.
An ungraded copy is worth around $6.20, a PSA 9 around $155.00, a PSA 10 (Gem Mint) around $438.16 and a pristine BGS 10 around $570.00. That's roughly a 71× 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 $6.20 and top grades reaching $438.16, 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.
