The neapolitan lira was the currency used in the Kingdom of Naples from 1815 to 1863. As the currency is no longer in use, there are several synonyms used to refer to it. One of the most commonly used synonyms is the carlino. The term stems from the coin that was used to represent the currency. In addition, the neapolitan lira is also referred to as piastra, which was a term used for similar currencies in other parts of Italy. Other synonyms for neapolitan lira include napoleon, scudo, and giulio. While these terms are not in common use today, they serve as reminders of the extensive history and cultural significance of the neapolitan lira.
