The 1967 Topps Mayo Smith #321 is a Baseball card released in 1967. Ungraded copies carry a market value of about $2.26.

An ungraded copy is worth around $2.26, a PSA 9 around $66.00, a PSA 10 (Gem Mint) around $530.50 and a pristine BGS 10 around $690.00. That's roughly a 235× 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 $2.26 and top grades reaching $530.50, 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.
