A dollar is a unit of money used in several countries like the US, Australia, Canada, and many more. The currency of the US is the United States Dollar (USD). Its symbol is $.
The word dollar comes from silver coins minted in 1518 in Bohemia. After passing through parts of Europe, and later, Spanish colonies around America, it finally arrived in the US. It was adopted as the official currency of the US in the 18th century, where it has been used ever since.
