The 1977 Topps Howard Porter White Back #102 is a Basketball card (White Back parallel) released in 1977. Ungraded copies carry a market value of about $1.13.
An ungraded copy is worth around $1.13, a PSA 9 around $26.46, a PSA 10 (Gem Mint) around $137.28 and a pristine BGS 10 around $178.00. That's roughly a 121× 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 $1.13 and top grades reaching $137.28, 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.
