A currency is a standardization of money in any form, in use or circulation as a medium of exchange, for example banknotes and coins. A more general definition is that a currency is a system of money in common use within a specific environment over time, especially for people in a nation state. Under this definition, the British Pound sterling (£), euros (€), Japanese yen (¥), and U.S. dollars (US$) are examples of (government-issued) fiat currencies. Currencies may act as stores of value and be traded between nations in foreign exchange markets, which determine the relative values of the different currencies. Currencies in this sense are either chosen by users or decreed by governments, and each type has limited boundaries of acceptance; i.e., legal tender laws may require a particular unit of account for payments to government agencies.

A virtual economy is an emergent economy existing in a virtual world, usually exchanging virtual goods in the context of an online game, particularly in massively multiplayer online games (MMOs). People enter these virtual economies for recreation and entertainment rather than necessity, which means that virtual economies lack the aspects of a real economy that are not considered to be "fun". However, some people do interact with virtual economies for "real" economic benefit.

A complementary currency is a currency or medium of exchange that is not necessarily a national currency, but that is thought of as supplementing or complementing national currencies. Complementary currencies are usually not legal tender and their use is based on agreement between the parties exchanging the currency. According to Jérôme Blanc of Laboratoire d'Économie de la Firme et des Institutions, complementary currencies aim to protect, stimulate or orientate the economy. They may also be used to advance particular social, environmental, or political goals.

A private currency is a currency issued by a private entity, be it an individual, a commercial business, a nonprofit or decentralized common enterprise.

Digital cryptocurrency is sometimes treated as an asset instead of a currency. Cryptocurrency is illegal as a currency in a few countries.
Demurrage is the cost associated with owning or holding currency over a given period. It is sometimes referred to as a carrying cost of money. For commodity money such as gold, demurrage is the cost of storing and securing the gold. For paper currency, it can take the form of a periodic tax, such as a stamp tax, on currency holdings. Demurrage is sometimes cited as economically advantageous, usually in the context of complementary currency systems.
