What Is Currency?

Currency can best be defined as tokens used as money in a country. In addition to the metal coins and paper banknotes, modern currency also includes checks drawn on bank accounts, money orders, traveler's checks, and will soon include electronic money or digital cash.
Typically currency refers to money that is legally designated as such by the governing body, but in some cultures, currency can refer to any object that has a perceived value and can be exchanged for other objects.
