An ungraded copy is worth around $5.27, a PSA 9 around $33.75, a PSA 10 (Gem Mint) around $167.13 and a pristine BGS 10 around $217.00. That's roughly a 32× 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 $5.27 and top grades reaching $167.13, 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.
