This 20 Pfennig coin from the Principality of Schwarzburg-Sondershausen shows the era with its Kriegsnotgeld (emergency war money) issuance. The obverse proudly displays a crowned two-headed eagle, symbolizing the principality's emblem, enclosed within a pearl circle and accentuated by the principality name. The reverse, consistent with its wartime relevance, showcases the 20 Pfennig denomination, circumscribed by the term "KRIEGSNOTGELD", all set within an intricately designed pearl rim.
