The 1975 Topps Mini Frank Duffy #448 is a Baseball card released in 1975. Ungraded copies carry a market value of about $1.89.
An ungraded copy is worth around $1.89, a PSA 9 around $33.99, a PSA 10 (Gem Mint) around $235.39 and a pristine BGS 10 around $306.00. That's roughly a 125× 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 $1.89 and top grades reaching $235.39, 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.
