The 1940 Play Ball Jack Knott #13 is a Baseball card released in 1940. Ungraded copies carry a market value of about $11.20.
An ungraded copy is worth around $11.20, a PSA 9 around $952.00, a PSA 10 (Gem Mint) around $3,749.95, a pristine BGS 10 around $4 and875.00. That's roughly a 335× 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 $11.20 and top grades reaching $3,749.95, 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.
