Which currency is used in the United States and is one of the world’s main reserve currencies?

The currency used in the United States and one of the world’s main reserve currencies is the United States dollar.

The dollar is divided into 100 cents and has the ISO 4217 code USD. The United States dollar is issued by the Federal Reserve System in the form of Federal Reserve notes, while the United States Mint produces coins. Its symbol is usually written as $.

The Coinage Act of 1792 established the dollar as the monetary unit of the United States. The name ultimately traces back to the European thaler, a large silver coin whose name spread through several languages. The American dollar was originally defined using a silver-based standard.

Today, the dollar’s importance extends far beyond the United States. It is widely used in international trade, central-bank reserves, financial markets, and as the official currency of several other countries and territories. The $ symbol can therefore require a country prefix in international contexts.
