The 1977 Topps Terry Harmon #388 is a Baseball card released in 1977. Ungraded copies carry a market value of about $1.38.
An ungraded copy is worth around $1.38, a PSA 9 around $113.50, a PSA 10 (Gem Mint) around $212.67 and a pristine BGS 10 around $276.00. That's roughly a 154× 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 $212.67, 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.
