<P> A currency ( from Middle English : curraunt , `` in circulation '' , from Latin : currens , - entis ) , in the most specific use of the word , refers to money in any form when in actual use or circulation as a medium of exchange , especially circulating banknotes and coins . A more general definition is that a currency is a system of money ( monetary units ) in common use , especially in a nation . Under this definition , US dollars , British pounds , Australian dollars , European euros and Russian ruble are examples of currency . These various currencies are recognized stores of value and are traded between nations in foreign exchange markets , which determine the relative values of the different currencies . Currencies in this sense are defined by governments , and each type has limited boundaries of acceptance . </P>
