In Germany, the name Groschen replaced Schilling as the common name for a 12 Pfennig coin. In the 18th Century it was used predominantly in the northern states as a coin worth 1/24 of a Reichsthaler (equal to 1/32 of a Conventionsthaler). In the 19th century, beginning in 1821 in Prussia, a new currency system was introduced in which the Groschen (often called the Silbergroschen or Neugroschen to distinguish it from older Groschen) was worth 1/30 of a Thaler. Following German unification and decimalization, the Groschen was replaced by the 10 Pfennig coin and Groschen remained a nickname for the 10 Pfennig coin until the introduction of the Euro.
