The term 'Currency Superseded by the Euro' refers to the Lira, which was the official currency of Italy until 2002 when it was replaced by the Euro. The Lira was a four-letter word and was used as the main form of currency in Italy for centuries. It was also used in other countries such as Malta, San Marino, and Vatican City. The Lira was replaced by the Euro in 2002, when Italy adopted the Euro as its official currency.
