The 1977 Topps Dave Cowens #90 is a Basketball card released in 1977. Ungraded copies carry a market value of about $2.00.

An ungraded copy is worth around $2.00, a PSA 9 around $30.29, a PSA 10 (Gem Mint) around $1,225.00, a pristine BGS 10 around $1 and593.00. That's roughly a 613× 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 $2.00 and top grades reaching $1,225.00, 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.
