Sondershausen was the former residence of the Schwarzburg-Sondershausen principality, and its municipal notgeld issues from 1921 reflect the broader Thuringian small-change crisis driven by coin hoarding during the postwar inflationary spiral. The reference suffix "1a-2/2" indicates this is the second of two known varieties within the first type — a distinction that matters more to completists than to casual collectors, but one that has real bearing on relative scarcity.

F. Menge is credited as designer, which was uncommon for notgeld of this denomination — most towns farmed out small-value issues to print shops without individual attribution.
