Currencies are the units of account that have different values around the world. Currencies are usually traded with the U.S dollar, the British pound, the Euro, the Japanese yen and the Swiss franc (the Euro has been the common currency used worldwide for decades). A currency in this sense is the currency in any shape or form when in actual use or circulation, particularly circulating coins and banknotes. Currencies are often bought and sold on stock markets and over the counter in the same way as shares on the stock market. Many countries issue their national currencies, but for convenience many countries also issue their local currencies which are known as local currency. One of the major differences between a currency such as the U.S. dollar and a country’s currency is the political influence of the issuing government.

As an example, the U.S. dollar is often the world’s currency primarily because it is the currency of the USA, but it also is a global currency due to the political influence of the United States. In other countries, like in Japan, the currency is often the Japanese Yen (which is the equivalent of the Euro). In recent years with the increase of Internet commerce, virtual currency exchanging websites have sprung up that allow people to buy and sell foreign coins and paper money over the Internet.

Usually, when a currency is being purchased or sold in the foreign currency exchange market, it is normally issued by the country whose currency it is. For example, when you are looking to purchase Euros with the U.S. dollar, you are usually buying the Euro rather than the dollar. Generally, if a country issues its own currency rather than the common or global currency that is usually issued by its central bank, then it is considered to be a special currency. In this case, the value of this currency is generally not equal to that of the national currency because the country issuing it issues it is considered to be the issuing government, and thus the value of its own currency is not typically reflective of the value of that of the national currency.
