The 1978 Kellogg's Tom Seaver #27 is a Baseball card released in 1978. Ungraded copies carry a market value of about $4.98.
An ungraded copy is worth around $4.98, a PSA 9 around $24.03, a PSA 10 (Gem Mint) around $480.47 and a pristine BGS 10 around $625.00. That's roughly a 96× 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 $4.98 and top grades reaching $480.47, 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.
