For most practical purposes, it is divided into 100 smaller cent (¢) units, but officially it can be divided into 1000 mills (₥). The circulating paper money consists of Federal Reserve Notes that are denominated in United States dollars (12 U.S.C. § 418). </P> <P> The U.S. dollar is commodity money of silver as enacted by the Coinage Act of 1792 which determined the dollar to be 371 ⁄ grain (24.1 g) pure or 416 grain (27.0 g) standard silver . Since the currency is the most used in international transactions, it is the world's primary reserve currency . Several countries use it as their official currency, and in many others it is the de facto currency . Besides the United States, it is also used as the sole currency in two British Overseas Territories in the Caribbean: the British Virgin Islands and Turks and Caicos Islands . A few countries use the Federal Reserve Notes for paper money, while still minting their own coins, or also accept U.S. dollar coins (such as the Susan B. Anthony dollar). As of July 12, 2017, there was approximately $1.56 trillion in circulation, of which $1.52 trillion was in Federal Reserve notes (the remaining $40 billion is in the form of coins). </P>
