United States dollar

The dollar (currency code USD) is the currency of the United States. It is normally abbreviated to the dollar sign $, or alternatively US$ to distinguish it from other dollar-denominated currencies. (Note: The $ symbol is also used by other countries for the peso). The U.S. dollar is divided into 100 (equal) cents.

The U.S. dollar today is the most-used currency in the world. Several countries use the U.S. dollar as their official currency, and many others allow it to be used in a de facto capacity. In 1995, over US$380 billion were in circulation, of which two-thirds was outside the United States. By 2005 that figure had doubled to nearly $760 billion with an estimated half to two-thirds being held outside the United States, which is an annual growth of about 6.6%.
