Stack's Bowers Galleries, legendary rare coin auction firm, is proud to announce that records were shattered in their September 3, 2026, offering of the Mack C. Chase Collection.
Rarity ratings provided courtesy of the Bust Half Nut Club Rarity Ratings Committee as published in their 2020 BHNC study report.
Obverse Description
Stars and 8 OBV. 20-s3. Same as s2 except all stars are now fairly sharp. The flat ones probably touched up with a better punch or by graving tools. In fact this entire obverse (except date) appears to have been refinished, causing slight changes in some measurements. A weakness at base of 8 in 20-s2 has now progressed to a thin break, with a small piece completely missing. There is a slight filling from chipping of the die, at the inside junction of the top and stand of 7.
Reverse Description
ED, AT and AM all close at base REV. X. A1LE, A2LE, A3UE. 50 C. is 2 mm. and well centered. A-A is slightly over ½ mm. I is centered under right side of T. Stripes 2 through 6 are usually filled. (64,63,63,62,62) R.3
