The 1975 Topps John Mengelt #12 is a Basketball card released in 1975. Ungraded copies carry a market value of about $1.38.

An ungraded copy is worth around $1.38, a PSA 9 around $34.86, a PSA 10 (Gem Mint) around $192.68 and a pristine BGS 10 around $250.00. That's roughly a 140× 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 $1.38 and top grades reaching $192.68, 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.
