The latest premier auction event from Colorado’s Mile High Card Company appears to be nothing short of the proverbial industry “monster,” presenting a staggering line-up of 1,883 lots consisting of the hobby’s finest high-grade sports and non-sport cards, as well as a select offering of sports memorabilia and Americana. Collectors familiar with the Centennial-based firm can expect to find the usual array of low-population GEMs from the hobby’s most trusted grading authorities, but even the Mile High staff was surprised to count, after all their hard work was done, a whopping total of 303 unique lots featuring single cards graded GEM MINT 10. The auction closes next week on October 6th.
