Graded by PSA NM-MT+ 8.5. This is very likely the rarest Topps regular issue card ever produced, the extremely rare White Letter variation of 1968 Topps #400 Mike McCormick. Nestled neatly in the old side pocket of the 1968 Topps set in this auction, we graded this newly discovered, fresh-to-the-hobby found GEM. To give a perspective on the rarity of this card, there are only a handful of high grade examples, the PSA web site indicating only 3 copies grade at the PSA NM-MT+ 8.5 level, with two higher. However, the pop report didn't differentiate between the yellow (regular) and the white letter (rare variation) until many years into the process. We do know a PSA MINT 9 example sold for over $9,600 early last year, which is the same exact card which sold for just under $6,000 a few years earlier. It is not often a very high grade example of this card comes up for sale, and at a PSA NM-MT+ 8.5 grade, this addition would jump the winning bidder up the Set Registry ranks.
