Little is known regarding the manner of distribution of the offered pair of 1928 PM6 Hall of Fame pinbacks. These 3/8" diameter treasures are undoubtedly rare as PSA has judged only 23 total examples from the ACC designation. Includes: 1.) Hornsby (EX) and 2.) Speaker (VG, a PSA 1 Speaker sold for $4,100 in August 2023 sale at another auction house.). Opening Bid $150.
