Two Sicilies ducat
In the mainland part of the kingdom, the ducat also replaced the Napoleonic lira.The subdivision and the coinage of the currency were simplified with respect to the pre-Napoleonic era: only three denominations survived.The ducat proper was the name of the gold coins, and curiously it did not exist as a single unit; the grana (singular: grano) was the name of the silver coins, itself also not existing as a single unit; the tornesel (Italian: tornese) was the name of the copper coins, which were worth half a grana.[2] The piastra was the unofficial name of the biggest silver coin, which had a value of 120 grana.When the Italian lira replaced the coinage of the House of Bourbon in 1861, a rate of 1 piastra = 5.1 lire was established.
