United States dollar ($):
Since 1792, US dollar is the official currency of USA and its territories as per its constitution. It is further sub-divided into 100 equal parts called cents. Cents are used in the form of coins whereas dollars of different denominations are circulated as paper currency notes. Although a dollar can be officially subdivided into 1000 parts, the concept remains as a mere theory rather than of any practical use.
In 1971, the convertibility of US dollar into any precious metal has been prohibited and since then US dollar has come to stay as de facto or fiat money. The US dollar is so extensively used worldwide that it is official currency in some countries whereas it is de facto currency in some other countries. De facto currency means that though it is not official currency, it is accepted by general public for transactions.
