The 1977 Topps John Mengelt White Back #101 is a Basketball card (White Back parallel) 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 $39.14, a PSA 10 (Gem Mint) around $219.93 and a pristine BGS 10 around $286.00. That's roughly a 110× 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 $219.93, 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.
