Graded by PSA GEM MINT 10. The 1971 Topps set is likely the most difficult set issued to obtain MINT cards, as the flush-to-the-border black edges reveal the slightest bit of wear. Obtaining PSA GEM MIMT 10 examples is exponentially even more difficult! Of the 258,054 cards from this issue graded by PSA, a miniscule 168 examples have ever graded GEM MINT 10. This recently graded Dave May example is GEM MINT with perfect corners, centering and surface with tremendous eye appeal. This is the ONLY example of card #493 ever graded PSA 10. Simply perfect.
