An ungraded copy is worth around $129.49, a PSA 9 around $232.32, a PSA 10 (Gem Mint) around $685.02 and a pristine BGS 10 around $891.00. That's roughly a 5.3× 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 $129.49 and top grades reaching $685.02, 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.
