The dollar is the legal tender in the United States –the country where it is minted- but also of other countries such as Ecuador, El Salvador or Zimbabwe. Moreover, the US dollar is the most common currency used by tourists.
The first silver dollars were issued in 1794 after the adoption of the “Coinage Act”, the decree that established the first American national mint and set the dollar as reference unit for the whole country.
As regards the national banking system, the Federal Reserve Act of 1913 established a central bank to help follow the rhythm of changes in the country’s financial need. The Federal Reserve Board created a new currency called Federal Reserve Notes. The first federal note was for ten dollars, created in 1914. Later, the Federal Reserve Board decided to lower the money manufacturing costs by reducing the official size of notes by 30%.
The design of notes would not change again until 1996, when a new series of improvements were introduced over a period of ten years to prevent counterfeiting.
