The euro banknotes

The euro was launched on 1 January 1999, when it became the currency of more than 300 million people in Europe. For the first three years it was an invisible currency, only used for accounting purposes, e.g. in electronic payments. Euro cash was not introduced until 1 January 2002, when it replaced, at fixed conversion rates, the banknotes and coins of the national currencies (Luxembourg franc, the Deutsche Mark, etc).
