Taler, large silver coin, introduced in 1486 in Tirol under the names of Unzialis (German Unze = ounce) or Guldiner or Guldengroschen (since it was coined as the silver equivalent to the Goldgulden). The name "taler" is derived from the Joachimsthaler (also called Guldengroschen), coined from 1520 onwards at Joachimsthal (Jachymov, Czech Republic) in Bohemia, the mint of the Counts of Schlick. The name quickly spread throughout Germany as well as other countries (e.g. rijksdaalder the Netherlands, tallero in northern Italy, rigsdaler in Danmark, dollar in the USA, Canada, tolar in Slovenia). In Austria, talers were often called after typical pictures on the coin or bore the names of popular monarchs ( Maria-Theresien-Taler). Talers were minted in Austria until 1856, in the form of Vereinstaler until 1867 (= common taler, common coin under the Austrian-German "Münzvertrag" treaty of 1857).
