Currency

A currency is a unit of exchange, facilitating the transfer of goods and services. It is a form of money, where money is an efficient medium of exchange, and it is also considered by several people as a store of value, created through a claim to its central bank assets. A currency zone is a country or region in which a specific currency is the dominant medium of exchange. To facilitate trade between currency zones, there are exchange rates i.e. prices at which currencies (and the goods and services of individual currency zones) can be exchanged against each other. Currencies can be classified as either floating currencies or fixed currencies based on their exchange rate regime. In common usage, currency sometimes refers to only paper money, as in "coins and currency", but this is misleading. Coins and paper money are both forms of currency.

Money

Money is any marketable good or token used by a society as a store of value, a medium of exchange, or a unit of account. Money objects can meet some or all of these needs. Since the needs arise naturally, societies organically create a money object when none exists. In other cases, a central authority creates a money object; this is more frequently the case in modern societies with paper money. (source: Wikipedia: money)
