The heller, or haller was a German coin valued at half a pfennig named after city of Hall (today Schwäbisch Hall). The coin was produced beginning in the 13th century as silver pfennig (Häller Pfennig). Heller was also the term for 1/100 of the Austro-Hungarian krone, the currency of Austria-Hungary from 1892 until after the demise of the Empire. The term heller (Czech: haléř, Slovak: halier) is also used for a coin valued at 1/100 of the Koruna in Czech Republic and Slovakia, as well as in the former Czechoslovakia.
