The United States dollar is the official currency of the United States and several other countries. The Coinage Act of 1792 introduced the U.S. dollar at par with the Spanish silver dollar, divided it into 100 cents, and authorized the minting of coins denominated in dollars and cents. U.S. banknotes are issued in the form of Federal Reserve Notes, popularly called greenbacks due to their predominantly green color.
The monetary policy of the United States is conducted by the Federal Reserve System, which acts as the nation's central bank.
The U.S. dollar was originally defined under a bimetallic standard of 371.25 grains fine silver or, from 1837, 23.22 grains fine gold, or $20.67 per troy ounce. The Gold Standard Act of 1900 linked the dollar solely to gold. From 1934, its equivalence to gold was revised to $35 per troy ounce. In 1971 all links to gold were repealed.
The U.S. dollar became an important international reserve currency after the First World War, and displaced the pound sterling as the world's primary reserve currency by the Bretton Woods Agreement towards the end of the Second World War. WikipediaКФА франкы жөнүндө
The West African CFA franc is the currency used by eight independent states in West Africa which make up the West African Economic and Monetary Union: Benin, Burkina Faso, Côte d'Ivoire, Guinea-Bissau, Mali, Niger, Senegal and Togo. These eight countries had a combined population of 105.7 million people in 2014, and a combined GDP of US$128.6 billion as of 2018.
The initialism CFA stands for Communauté Financière Africaine. The currency is issued by the Central Bank of West African States, located in Dakar, Senegal, for the members of the UEMOA. The franc is nominally subdivided into 100 centimes but no coins or banknotes denominated in centimes have ever been issued. The production of CFA franc notes has been carried out at Chamalières by the Bank of France since its creation in 1945.
The Central African CFA franc is of equal value to the West African CFA franc, and is in circulation in several central African states. They are both commonly referred to as the CFA franc.
In December 2019 it was announced that the West African CFA franc would be reformed, which will include renaming it the eco and reducing France's role in the currency. Wikipedia
