Do you know where the word ‘dollar’ comes from?
The dollar is one of the most common currencies in the world used by the US, Australia, Canada, Fiji, New Zealand, and Singapore to name a few. The origin of the dollar, also the Slovenian tolar, is from a coin called the Joachimsthaler, shortened to Thaler (or daler in early Flemish or Low German), named after the valley in which the silver it was made from was mined, the Joachimsthal, literally ‘Joachim’s valley’. The term began to be used in other languages, especially Dutch, and was later applied to the most widely used coin in the American colonies. In 1792, it was adopted as the name of the US monetary unit.
