The 1971 Kellogg's Billy Grabarkewitz #56 is a Baseball card released in 1971. Ungraded copies carry a market value of about $8.00.
An ungraded copy is worth around $8.00, a PSA 9 around $68.38, a PSA 10 (Gem Mint) around $961.30, a pristine BGS 10 around $1 and250.00. That's roughly a 120× 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 $8.00 and top grades reaching $961.30, 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.
