Grano Coin: Etymology, Neapolitan Monetary System

Illustrated Specimen Details: 1 Grano (Kingdom of Naples)

Example Specimen: 1 grano, 1789 (Kingdom of Naples)

Authority & Heraldry: This copper 1 grano coin was minted under Ferdinand IV (Ferdinando di Borbone-Due Sicilie), who ruled the Kingdom of Naples across several periods (1759-1799, 1799-1806, and 1815-1816). The obverse features a classic portrait of the king, encircled by the Latin inscription "FERDINAN IV SICILIAR REX" (Ferdinand IV, Sicilian King). Below the portrait is the symbol "P.", the signature mark of engraver Domenico Perger. The reverse explicitly states the value in a dual format: "VN GRANO / CAVALLI 12", establishing that 1 grano equals 12 cavalli. The letters "CC" flank the number 12, a characteristic detail of the 1788-1800 series, which also featured other enigmatic abbreviations like PCC, PAC, and AP.

The Grano as a Coin Name. The grano (plural: grana or grani) was a foundational historical coin used across the states of Southern Italy from the 15th-19th centuries. The name is derived from the Latin word "granum", meaning "grain" or "seed", reflecting the medieval European practice of directly linking coin values to precise units of weight. While standard grana were minted in copper or billon for everyday use, larger denominations (such as 8, 10, or 15 grana) were struck in silver.

Historical Background and Monetary Evolution

The grano first emerged in the territories of the Kingdom of Naples in the late 1490s as a substantial copper coin weighing more than 4 grams. It quickly became one of the most important fractional denominations in Southern Italy, serving as a vital medium of exchange for market transactions, wages, and taxes under Spanish, Austrian, Bourbon, and Napoleonic administrations.

The Neapolitan and Sicilian Systems

In the Kingdom of Naples, the monetary structure dictated that 120 grana equaled 1 Neapolitan piastra. Interestingly, the Neapolitan government never actually minted a coin labeled as a "piastra." Instead, the physical representation of this major monetary unit was a large, heavy silver coin (weighing 27.5 g) that simply bore the denomination of 120 grana. The grano itself was further subdivided into smaller copper units, equaling exactly 2 tornesi or 12 cavalli.

The neighboring Kingdom of Sicily also issued its own grana, though under a different accounting scale, where 240 grana constituted 1 Sicilian piastra. Following the political unification of the two territories in 1816 to form the Kingdom of the Two Sicilies, the currency was standardized. The new unified piastra was set at a rate of 120 grana.

The Order of Malta and Final Years

Beyond mainland Italy and Sicily, the Sovereign Military Hospitaller Order of Saint John of Jerusalem, of Rhodes and of Malta also utilized the grano system during the 16th-18th centuries. The Maltese grano was valued at 1/240 of a scudo and is highly sought after by modern numismatists. Starting in 1967, the Order revived the denomination exclusively for modern souvenir coinage.

In Italy, the historical grano continued to be minted and circulated until the late 19th century, when the political unification of Italy ultimately led to the abolition of all regional currencies in favor of the newly established Italian lira.
