The 1970 Kellogg's Leroy Kelly #31 is a Football card released in 1970. Ungraded copies carry a market value of about $3.49.
An ungraded copy is worth around $3.49, a PSA 9 around $23.05, a PSA 10 (Gem Mint) around $172.87 and a pristine BGS 10 around $225.00. That's roughly a 50× 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 $3.49 and top grades reaching $172.87, 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.
