Issued in January 1922 as part of the Weimar Republic’s definitive series depicting numerals, workers, and posthorns, this 100 Pfennig stamp features a miner holding a lantern and pickaxe, symbolizing the labor force central to the German industrial economy during the early post-war years. Designed by Paul Neu and printed by Reichsdruckerei in Berlin, the stamp was produced using typography and issued in a dark greenish olive to dark olive green color scheme. Measuring 22 x 26 mm and perforated comb 14 x 14¼, it carries the waffle watermark in upright orientation. Intended for high-denomination postal rates during the extreme inflation period of 1922–1923, this issue was widely used until it was withdrawn from circulation on September 30, 1923. The stamp’s strong iconography of industrial workers reflects the economic hardship and societal focus on productivity during the early Weimar era.
