The 1977 Kelloggs Cesar Geronimo #40 is a Baseball card released in 1977. Ungraded copies carry a market value of about $3.82.
An ungraded copy is worth around $3.82, a PSA 9 around $49.99, a PSA 10 (Gem Mint) around $499.99 and a pristine BGS 10 around $650.00. That's roughly a 131× 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 $3.82 and top grades reaching $499.99, 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.
