Did you know?

In the early 1500s, much of the silver used to mint coins in Europe came from the mountains on the current border of Germany and Czechia. One such German coin was the Joachimsthaler, or Thaler for short, named after the town of Sankt Joachimstal. Shortly afterward the Dutch form daler was borrowed into English and applied to similar coins in the North American colonies. When the United States settled on an official monetary unit in 1785, they chose the name (and spelling) dollar.
