Sicilian piastra

In the late 18th century, coins were circulating in denominations of 3 piccoli, 1, 2, 10 and 20 grana, 2, 3, 4 and 6 tari, 1 piastra and 1 oncia.

Following the adoption of the unified currency for the two Sicilies, copper coins were issued in 1835 and 1836 bearing the name "Siciliana", in denominations of ½, 1, 2, 5 and 10 grana.

A Sicilian coin commonly available for sale today is the 120 grana silver piece, weighing an ounce.

However, in 1823 George Crabb, in his Universal Technological Dictionary Volume 2, in addition to supporting the above relative values of onze, tarì and grano in accounting, lists 120 grana as equivalent to one fiorino.

Crabb also lists the ponto, the carlino, the ducat and the scudo or crown and their equivalence to the grano, however no mention of the piastre.
