1937-D 50C MS67 Certification #37240373, PCGS #6602
The 1937-D and 1937-S are very comparable in terms of mintage and rarity in mint state and Gem condition. The 1937-D is rarer than the 1936-D and considerably rarer than the 1939-D, but it is not quite as rare as the 1938-D and the 1934-D and 1935-D are way rarer than any of the other D-Mints including the 1937-D. I have seen numerous original uncirculated rolls of both the 1937-D and 1937-S "back in the day," i.e. the 1970s when rolls of coins from the 1930S were still trading intact in the numismatic market place. The 1937-D is usually well struck and luster can be quite frosty.
