50 Pfennig

Altenburg's emergency small change — Notgeld, in the strict sense — was printed by the Altenburger Spielkartenfabrik, a playing card manufacturer that had been producing finely printed paper goods for decades before the hyperinflationary crisis forced German municipalities to improvise their own coinage substitutes. The firm was a logical local choice: the precision color work required for card printing translated directly to the demands of small-denomination notes.

1921 sits in the relatively stable window before the catastrophic inflation of 1922–23, meaning this issue was a response to coin shortages rather than currency collapse. Most Thuringian Notgeld of this period was redeemed quickly once federal coinage supplies recovered, which has kept genuine circulated survivors rarer than the collector-targeted series produced in the same years.
