The Measure of Corsica
1734 Genoese Zecchino
Currency
Creating a new national currency had been one of the first concerns of the newly crowned King Theodore I, but it had been a rocky start. Theodore’s first mint struck 2½ and 5
soldi coins which were notionally made of billon, a copper-silver alloy In practice, however, there was little or no silver content in these issues. The Corsicans joked that the “TR” inscribed on the coins for “Theodore Rex” actually stood for
tutti rami, “all copper,” and the mint workers refused to be paid in the coins they themselves had made. They were more valuable as collectibles
outside Corsica than as currency within it. A mint in Naples began churning out counterfeit coins to be sold as curios, although since these fakes had no less silver than the genuine article it’s not clear if they really ought to be considered “counterfeit.” Theodore's government also minted a 1
lira (20
soldi) coin weighing around 3.48 grams which
did actually contain silver, but the fineness and weight varied considerably, with some specimens barely over .500 fineness.
[A] As actual circulating currency, the revolutionary currency must be considered a failure; most royalist soldiers were paid with Genoese
lire and various foreign coins smuggled into Corsica.
Corsica was not alone in its monetary woes. At the outset of the Corsican Revolution the Genoese
lira contained 5.23 grams of “8/9” silver (.889 fine), for an actual fine silver content of about 4.65 grams. In 1746, however, in the face of military and financial collapse, the Genoese
lira was devalued to 3.86 grams of silver. The fineness was eventually reestablished at .889 but not the size, and for the rest of the century the Genoese
lira was a 4.16g coin containing 3.70 grams of silver. The Corsicans may have been directly contributing to this instability through counterfeiting in the late 1740s, as there are an unusually large number of specimens of debased and low-quality "pre-1746"
lire; one must remember that Theodore's first head minter was himself an infamous counterfeiter.
The mere fact of independence did not succeed in rehabilitating the poor reputation of Corsican currency, and for most of the reign of Theodore I Genoese, Tuscan, and other foreign coins were more common than the kingdom's own currency. Increasing the silver content did not help, as few believed the coins had real value and there were by this time large numbers of worthless counterfeit "curio" copies floating about. Late in the reign of Theodore I, the Frediani-Paoli ministry proposed a fresh start - the replacement of the old, troubled
lira with a completely new design to make a clean break from the past. This "
lira nuova" would be the same size and fineness of the Tuscan
lira, which give it the benefit of easy convertibility with the currency used at Livorno, Corsica's most important commercial partner. The result was a 4.64 gram coin with a silver content of 5/6 (.833 fine), containing 3.86 grams of silver. The
lira nuova was worth about 0.86 French livres, and in the late 18th century it traded at approximately 30 to the British pound sterling.
Only a limited number of new
lire were minted under Theodore I, but the overhaul was continued and expanded during the reign of Federico. The
lira was not the only problem - its subdivisions, the TR billon coins, had just as bad a reputation and even the 2½-
soldi piece was inadequate for small purchases. These coins were given superficial redesigns, their fineness was fixed at .012, and they were supplemented by three new copper denominations: a 1-
soldo coin, a
soldino (half-
soldo or 6
denari), and a
sestino (⅙ of a
soldo or 2
denari). These coins were slow to catch on, as the memory of worthless revolutionary copper currency still lingered in Corsica.
None of these denominations were large enough for the purposes of government accounting or bulk trade. In the early years such transactions were usually calculated in “sequins” - that is, the Genoese gold
zecchino - which was worth 13½ Genoese
lire. Theodore was said to have handed out "a gun and a sequin" to his militiamen, which amounted to about a month's wages, but it is unlikely this ever took the form of actual gold
zecchini. In part because of fluctuations in the gold-silver ratio, the
zecchino was replaced as the government's
de facto large unit of account during the reign of Federico and replaced with the Corsican
scudo d’argento, which was defined as equal to 6
lire nuove. This unit initially existed only on paper; Federico planned to actually mint such coins but the first was not struck until after his death. The physical
scudo d'argento minted under Theodore II was a 27.8 gram coin of 5/6 fineness. Containing 23.16g fine silver, it was very close to the Austrian
Conventionsthaler of 23.39g fine silver. In Corsica it was known as a
teone (“Big Theo”) because of its large size - nearly one ounce - and because it was struck with the image of the king, making it the first Corsican coin to feature a royal portrait. Another coin of middling value was added in the 1780s, the half-
lira (10
soldi) consisting of .625 fine silver.

The Corsican government also established two gold denominations in the 1780s, the
scudo d’oro and the
doppia, initially defined as equal to 12 and 24
lire (2 and 4
scudi d'argento) respectively. Only the
doppia was actually minted in the 18th century, while the
scudo d'oro remained purely a unit of account. The Corsican
doppia was a 6.74 gram coin of 11/12 (.917 fine) gold which bore a portrait of the king on one side and the great arms of the kingdom on the other. Containing 6.18g of fine gold, the Corsican
doppia can be compared to other Italian
doppie like those of Milan (6.21g), Parma (6.36g), and Lucca (6.90g), as well as other contemporary gold coins like the Spanish doubloon (6.04g) and the French
Louis d’or (~7.45g).
[1] This gold content was based on a gold-silver ratio of 15 to 1, but fluctuations in the relative value of gold eventually forced the government to revalue its gold currency and break the simple 2 to 1 convertibility between the
scudo d’argento and the
scudo d’oro. Although the
doppia was actual legal tender which did see some limited circulation in Corsica, it was primarily useful as a means of international legitimation. Having one's portrait on a large gold coin was a nearly universal trait of "proper" European monarchs, and Theodore II was the first Corsican king who was able to join this exclusive club.
Weights and Measures
Corsica continued to use the Genoese pound (
libbra genovesca) of approximately 317 grams, which was about 70% of the weight of an English pound. Also common was the
rotolo of 1½
libbre (~475.5 g) which is sometimes confusingly referred to in foreign sources as the “Corsican pound” because it more closely resembled the pound measurements of England (453.6 g), Spain (460 g), and France (489.5 g).
[B] Bulk goods were usually measured in
cantari, with one
cantaro equal to 150
libbre or 100
rotoli. The standard ratio at Ajaccio was 105 English pounds to 100
rotoli (one
cantaro), which was only off by about 78 grams.
Likewise, Genoese length measurements remained in use. The most important units were the
palma (“palm”, about 81.4% of the length of an English foot), the
passo (“pace,” equal to 6
palmi or ~1½ meters), and the
miglio (“mile,” equal to 6000
palmi or 1000
passi, about 92.5% of an English mile). Another unit, the
cannella (equal to 2
passi, 12
palmi, or just under 3 meters), was preferred for ground and architectural measurement, and the
cannella quadrata (about 8.86 square meters) was used for measuring area. Because the surveys of the island in the 1740s and 1750s had been performed by the French, however, the
Catasto Reale also used the
arpento (Paris arpent) to measure land area, which was equal to about 576
cannelle quadrate or 1.26 acres.

Footnotes
[1] The Spanish doubloon was the original basis for all these coins. What we know as a “doubloon” in English was a 2-
escudo gold coin - thus
doblón, “double.” This in turn gave its name to the Italian
doppia and inspired the minting of other similarly-sized gold coins across Europe. The French
Louis d’or was originally a direct copy of the
doblón.
Timeline Notes
[A] The historical Theodoran
lira seems to be exceptionally rare. While the lesser "TR" coins appear on auction sites (sometimes for thousands of dollars each), I have yet to see an actual picture of a Theodoran
lira, only sketches. I do not actually know what the size or fineness of this coin was, although it is universally described as "silver" so it must have had at least some silver in it, unlike the "billon" coins which had little or none. The weight and fineness figures for the Theodoran
lira given above are actually those of the
Paolist lira minted in the 1760s; I doubt Theodore's was the same, but we can at least know that it was possible to strike such a coin on Corsica. Paoli's republic minted 1, 2, and 4
soldi coins, as well as
lire and half-
lire.
[B]
Rotolo comes from the Arabic
rutl, a unit of measurement used in the Middle East and North Africa which itself comes from the Ancient Greek
lítra, which is also the root of
litre and is etymologically related to a variety of other measurements (
libra,
livre, etc).
[C] The next update will concern Corsica’s financial situation, and I thought it might be helpful to write a mini-update establishing what types of exchange we’re actually talking about before we dive into debt, budgets, and banking. I’ve barely mentioned currency at all since the
Governance and Indifference update which was posted back in 2017, which was probably an oversight. The system above is fairly typical for this time period: Most European countries still based their silver/copper currency on the old Carolingian system of 1 libra = 20 solidi = 240 denari, differing mainly in how these units were subdivided. The
scudo was less well-defined; some other Italian states had a silver
scudo which was worth 6
lire, but in some places it was 8
lire instead, and in Sardinia-Piedmont a
scudo was only worth 2½
lire. The pre-decimalization era must have been a confusing time to be alive.
