The 1971 Topps set is definitely the most challenging set to complete in high grade of all the 1970s sets, and arguably one of the most difficult sets to complete in high grade of all the Topps issues. However, this offered example of the Willie Mays card is a true high grade specimen. Four sharp corners, well-centered and a crisp focused image are the bedrocks of the card graded by PSA as MINT 9. Of the almost 2,000 examples of the 1971 Topps #630 Mays graded to this date by PSA, this is only one of 12 examples graded PSA MINT 9, with not a single example grading higher. It has been almost a full year since the last example publicly traded hands. PSA MINT 9.
