Kingdom of Italy silver lira

The silver lira was an official currency denomination struck for the unified Kingdom of Italy following the unification of the Italian peninsula in 1861. As a decimal coin, the lira was subdivided into 100 centesimi. Its name derives from the libra, the largest unit of the Carolingian monetary system employed in Western Europe from the eighth century onwards. Issued under the Italian crown, the coinage carries the portrait of the reigning monarch.

The monetary standard of the lira originated in 1807 under the Napoleonic Kingdom of Italy, when it was introduced at par with the French franc. Following the collapse of the Napoleonic kingdom in 1814, the lira was gradually adopted across the Italian peninsula, replacing the diverse currencies of earlier regional states such as the Genoese lira, the Sardinian scudo, the Tuscan fiorino, the Neapolitan lira, and the Papal lira. After Italian national unification in 1861, Italy entered the Latin Monetary Union in 1865, fixing the lira at parity with the French, Belgian, and Swiss francs until the outbreak of the First World War disrupted the union.

Early modern Italian coinage closely mirrored the style and decimal divisions of contemporary French francs. In its physical metallic specification, the lira was defined by an intrinsic standard of 4.5 grams of fine silver, corresponding to a gold-to-silver ratio of 15.5 against 0.29032 grams of fine gold. On minted coins, the currency denomination was regularly denoted by the abbreviation "L.", accompanying the royal portrait of the sovereign.
