The Euro is the currency used by nineteen countries in the European Union. Euro coins and banknotes began to circulate on 1 January 2002. However, their use began three years earlier as an electronic currency. All coins have a common face, while the other face is drawn by each Member State and includes symbols representing the origin and nationality of each country. The euro is the second largest reserve currency and is also the second most used currency in the world. The idea of introducing a single currency in the countries of Europe dates back to the 70s. Initially it had to be called ECU (European Currency Unit). However, ECU is also the designation of an old French currency, and one reason for the name changeover to euro was to favor no country or language.
The Real is the official currency of Brazil. After successive monetary exchanges, Brazil adopted the real on July 1, 1994. The name chosen coincides with the name of the first currency of Brazil, a currency used by the empire of Portugal in all its colonies. The real is the sixteenth most traded currency in the world. It is estimated that today there are more than eight million real coins lost. The real 1 note is so rare (it stopped being issued in 2005) that some believe that it gives luck. For this reason many bring one of these notes in their wallets. Collectors even pay twenty reais to get one of these notes. Despite this apparent rarity it is estimated that there are 150 million notes of 1 real still in circulation in Brazil.
