Did you know?

In the mountains of Bohemia is the small town of Jáchymov. In the early 16th century, the town was known by its German name, Sankt Joachimstal. At that time, a silver mine was opened nearby, and coins were minted to which the name joachimstaler was applied. In German this was shortened to Taler. Shortly afterward the Dutch or Low German form daler was borrowed into English to refer to the Taler and other coins that were patterned after it, such as the Spanish peso, which circulated widely in Britain’s North American colonies. Our modern word dollar is a different spelling of this daler. When the newly independent American colonies settled on an official monetary unit in 1785, they chose the name dollar.
