The 1975 Topps Mini Harmon Killebrew #640 is a Baseball card released in 1975. Ungraded copies carry a market value of about $4.99.
An ungraded copy is worth around $4.99, a PSA 9 around $362.83, a PSA 10 (Gem Mint) around $608.78 and a pristine BGS 10 around $791.00. That's roughly a 122× 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 $4.99 and top grades reaching $608.78, 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.
