The 1964 Topps Bobby Knoop / Bob Lee #502 is a Baseball card released in 1964. Ungraded copies carry a market value of about $3.19.
An ungraded copy is worth around $3.19, a PSA 9 around $83.90, a PSA 10 (Gem Mint) around $520.43 and a pristine BGS 10 around $677.00. That's roughly a 163× 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 $3.19 and top grades reaching $520.43, 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.
