An ungraded copy is worth around $15.11, a PSA 9 around $39.19, a PSA 10 (Gem Mint) around $172.15 and a pristine BGS 10 around $224.00. That's roughly a 11× 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 $15.11 and top grades reaching $172.15, 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.
