Byzantine Coinage

Byzantine currency, money used in the Eastern Roman Empire after the fall of the West, consisted of mainly two types of coins: the gold solidus and a variety of clearly valued bronze coins. By the end of the empire the currency was issued only in silver stavrata and minor copper coins with no gold issue.

The East Roman or Byzantine Empire established and operated several mints throughout its history. Aside from the main metropolitan mint in the capital, Constantinople, a varying number of provincial mints were also established in other urban centres, especially during the 6th century. Most provincial mints except for Syracuse were closed or lost to invasions by the mid-7th century. After the loss of Syracuse in 878, Constantinople became the sole mint for gold and silver coinage until the late 11th century, when major provincial mints began to re-appear. Many mints, both imperial and, as the Byzantine world fragmented, belonging to autonomous local rulers, were operated in the 12th to 14th centuries. Constantinople and Trebizond, the seat of the independent Empire of Trebizond (1204–1461), survived until their conquest by the Ottoman Turks in the mid-15th century.

Iconography

Early Byzantine coins continue the late Greco-Roman conventions: on the obverse the head of the Emperor, now full face rather than in profile, and on the reverse, usually a Christian symbol such as the cross, or a Victory or an angel (the two tending to merge into one another). The gold coins of Justinian II departed from these stable conventions by putting a bust of Christ on the obverse, and a half or full-length portrait of the Emperor on the reverse. These innovations incidentally had the effect of leading the Islamic Caliph Abd al-Malik, who had previously copied Byzantine styles but replacing Christian symbols with Islamic equivalents, finally to develop a distinctive Islamic style, with only lettering on both sides. This was then used on nearly all Islamic coinage until the modern period.

The type of Justinian II was revived after the end of Iconoclasm, and with variations remained the norm until the end of the Empire.

In the 10th century, so-called "anonymous folles" were struck instead of the earlier coins depicting the emperor. The anonymous folles featured the bust of Jesus on the obverse and the inscription "XRISTUS/bASILEU/bASILE", which translates to "Christ, Emperor of Emperors"

Byzantine coins followed, and took to the furthest extreme, the tendency of precious metal coinage to get thinner and wider as time goes on. Late Byzantine gold coins became thin wafers that could be bent by hand.

The Byzantine coinage had a prestige that lasted until near the end of the Empire. European rulers, once they again started issuing their own coins, tended to follow a simplified version of Byzantine patterns, with full face ruler portraits on the obverse.

Denominations

The start of what is viewed as Byzantine currency by numismatics began with the monetary reform of Anastasius in 498, who reformed the late Roman Empire coinage system which consisted of the gold ''solidus'' and the bronze ''nummi''. The '' nummus'' was an extremely small bronze coin, at about 8–10 mm, weight of 0.56 g making it at 576 to the Roman pound which was inconvenient because a large number of them were required even for small transactions.

New bronze coins, multiples of the ''nummus'' were introduced, such as the 40 ''nummi'' (also known as the ''follis''), 20 ''nummi'' (also known as the ''semifollis''), 10 ''nummi'' (also known as the ''decanummium'', and 5 ''nummi'' coins (also known as the ''pentanummium''); other denominations were occasionally produced. The obverse (front) of these coins featured a highly stylized portrait of the emperor while the reverse (back) featured the value of the denomination represented according to the Greek numbering system (M=40, Λ=30, K=20, I=10, E=5). Silver coins were rarely produced.

The only regularly issued silver coin was the Hexagram first issued by Heraclius in 615 which lasted until the end of the 7th century, minted in varying fineness with a weight generally between 7.5 and 8.5 grams. It was succeeded by the initially ceremonial ''miliaresion'' established by Leo III the Isaurian in ca. 720, which became standard issue from ca. 830 on and until the late 11th century, when it was discontinued after being severely debased. Small transactions were conducted with bronze coinage throughout this period.

The gold ''solidus'' or '' nomisma'' remained a standard of international commerce until the 11th century, when it began to be debased under successive emperors beginning in the 1030s under the emperor Romanos Argyros (1028–1034). Until that time, the fineness of the gold remained consistent at about 0.955–0.980.

The Byzantine monetary system changed during the 7th century when the 40 ''nummi'' (also known as the ''follis''), now significantly smaller, became the only bronze coin to be regularly issued. Although Justinian II (685–695 and 705–711) attempted a restoration of the ''follis'' size of Justinian I, the ''follis'' continued to slowly decrease in size.

In the early 9th century, a three-fourths-weight solidus was issued in parallel with a full-weight solidus, both preserving the standard of fineness, under a failed plan to force the market to accept the underweight coins at the value of the full weight coins. The ¹¹⁄₁₂ weight coin was called a '' tetarteron'' (a Greek comparative adjective, literally "fourth-er"), and the full weight solidus was called the ''histamenon''. The ''tetarteron'' was unpopular and was only sporadically reissued during the 10th century. The full weight solidus was struck at 72 to the Roman pound, roughly 4.48 grams in weight. There were also solidi of weight reduced by one ''siliqua'' issued for trade with the Near East. These reduced solidi, with a star both on obverse and reverse, weighed about 4.25 g.

The Byzantine solidus was valued in Western Europe, where it became known as the ''bezant'', a corruption of ''Byzantium''. The term bezant then became the name for the heraldic symbol of a roundel, tincture or – i.e. a gold disc.

Alexius I reforms

Former money changer Michael IV the Paphlagonian (1034–41) assumed the throne of Byzantium in 1034 and began the slow process of debasing both the ''tetarteron nomisma'' and the ''histamenon nomisma''. The debasement was gradual at first, but then accelerated rapidly. about 21 carats (87.5% pure) during the reign of Constantine IX (1042–1055), 18 carats (75%) under Constantine X (1059–1067), 16 carats (66.7%) under Romanus IV (1068–1071), 14 carats (58%) under Michael VII (1071–1078), 8 carats (33%) under Nicephorus III (1078–1081) and 0 to 8 carats during the first eleven years of the reign of Alexius I (1081–1118). Under Alexius I Comnenus (1081–1118) the debased solidus (''tetarteron'' and ''histamenon'') was discontinued and a gold coinage of higher fineness (generally .900-.950) was established, commonly called the ''hyperpyron'' at 4.45 grs. The ''hyperpyron'' was slightly smaller than the solidus.

It was introduced along with the electrum '' aspron trachy'' worth a third of a ''hyperpyron'' and about 25% gold and 75% silver, the billon ''aspron trachy'' or '' stamenon'' valued at 48 to the hyperpyron and with 7% silver wash and the copper '' tetarteron'' and '' noummion'' worth 18 and 36 to the billon ''aspron trachy''.

Andronicus II reforms

During Andronicus II's reign he instituted new denominations based on the hyperpyron. They were the silver miliaresion or basilika at 12 to the hyperpyron and the billon politika at 96 per hyperpyron,
along with the copper assaria, tournesia and follara.
The ''basilikon'' was a copy of the Venetian ducat and circulated from 1304 for fifty years.

The ''hyperpyron'' remained in regular issue and circulation until the 1350s, remaining in use thereafter only as a money of account. After 1400, Byzantine coinage became insignificant, as Italian money became the predominant circulating coinage.

These ''scyphate'' (cup-shaped) coins known as ''trachy'' were issued in both electrum (debased gold) and billon (debased silver). The exact reason for such coins is not known, although it is usually theorized that they were shaped for easier stacking.

1367 reform

During this last phase of Byzantine coinage gold issues were discontinued and a regular silver issue was commenced. The denomination was the Stavraton issued in 1, , and stavraton. Also issued were the copper follaro and tornesse.

Buying power

It is possible to get some small snapshots in time, specific to region, culture and local inflation. The literary world is littered with references to prices from different time frames. A good portion of them may be inaccurate or tainted by translation.

At Jerusalem in the sixth century a building worker received solidus per day, that is 21 folles. solidus was earned by a casual labourer at Alexandria in the early seventh century. A family's vegetable allowance for one day cost 5 folles. A pound of fish 6 folles, a loaf of bread was 3 folles worth at a time of shortage. The cheapest blanket was worth solidus, a second-hand cloak 1 solidus, and a donkey 3 or 4 solidi.Mango, Cyril. (1980) "Byzantium: the empire of New Rome". Weidenfeld and Nicolson. Page 40.
