The denarius was the standard Roman silver coin from its introduction in the Second Punic War c. 211 BC to the reign of Gordian III, when it was gradually replaced by the antoninianus. It continued to be minted in very small quantities, likely for ceremonial purposes, until and through the Tetrarchy (293–313).
Diocletian, nicknamed Jovius, was Roman emperor from 284 until his abdication in 305. He was born Diocles to a family of low status in the Roman province of Dalmatia. Diocles rose through the ranks of the military early in his career, eventually becoming a cavalry commander for the army of Emperor Carus. After the deaths of Carus and his son Numerian on a campaign in Persia, Diocles was proclaimed emperor by the troops, taking the name Diocletianus. The title was also claimed by Carus's surviving son, Carinus, but Diocletian defeated him in the Battle of the Margus.
An edict is a decree or announcement of a law, often associated with monarchism, but it can be under any official authority. Synonyms include "dictum" and "pronouncement". Edict derives from the Latin edictum.
The sestertius or sesterce was an ancient Roman coin. During the Roman Republic it was a small, silver coin issued only on rare occasions. During the Roman Empire it was a large brass coin.
The antoninianus or pre-reform radiate was a coin used during the Roman Empire thought to have been valued at 2 denarii. It was initially silver, but was slowly debased to bronze with a minimal silver content. The coin was introduced by Caracalla in early 215 AD. It was silver, similar to the denarius, except that it was slightly larger and featured the emperor wearing a radiate crown, indicating it was a double denomination. Antoniniani depicting women featured the bust resting upon a crescent moon.
Roman currency for most of Roman history consisted of gold, silver, bronze, orichalcum and copper coinage. From its introduction during the Republic, in the third century BC, through Imperial times, Roman currency saw many changes in form, denomination, and composition. A feature was the inflationary debasement and replacement of coins over the centuries. Notable examples of this followed the reforms of Diocletian. This trend continued with Byzantine currency.
Byzantine currency, money used in the Eastern Roman Empire after the fall of the West, consisted of mainly two types of coins: gold solidi and hyperpyra and a variety of clearly valued bronze coins. By the 15th century, the currency was issued only in debased silver stavrata and minor copper coins with no gold issue.
The solidus or nomisma was a highly pure gold coin issued in the Later Roman Empire and Byzantine Empire. The early 4th century saw the solidus introduced in mintage as a successor to the aureus, which was permanently replaced thereafter by the new coin, whose weight of about 4.5 grams remained relatively constant for seven centuries.
The aureus was a gold coin of ancient Rome originally valued at 25 pure silver denarii. The aureus was regularly issued from the 1st century BC to the beginning of the 4th century AD, when it was replaced by the solidus. The aureus was about the same size as the denarius, but heavier.
£sd, spoken as "pounds, shillings and pence", is the popular name for the pre-decimal currencies once common throughout Europe. The abbreviation originates from the Latin currency denominations librae, solidi, and denarii. In the United Kingdom, these were referred to as pounds, shillings, and pence.
The siliqua is the modern name—given without any ancient evidence to confirm the designation—to small, thin, Roman silver coins produced in the 4th century and later. When the coins were in circulation, the Latin word siliqua was a unit of weight or value defined by one late Roman writer as one twenty-fourth of a Roman solidus.
"Siliqua vicesima quarta pars solidi est, ab arbore, cuius semen est, vocabulum tenens."
A siliqua is one twenty-fourth of a solidus, having its name from the tree of which it is the seed.
The argenteus was a silver coin produced by the Roman Empire from the time of Diocletian's coinage reform in AD 294 to ca. AD 310. It was of similar weight and fineness to the denarius of the time of Nero. The coin was produced at a theoretical weight of 1/96th of a Roman pound, as indicated by the Roman numeral XCVI on the coin's reverse.
Roman Republican currency is the coinage struck by the various magistrates of the Roman Republic, to be used as legal tender. In modern times, the abbreviation RRC, "Roman Republican Coinage" originally the name of a reference work on the topic by Michael H. Crawford, has come to be used as an identifying tag for coins assigned a number in that work, such as RRC 367.
The follis was a type of coin in the Roman and Byzantine traditions.
Silver coins are one of the oldest mass-produced form of coinage. Silver has been used as a coinage metal since the times of the Greeks; their silver drachmas were popular trade coins. The ancient Persians used silver coins between 612–330 BC. Before 1797, British pennies were made of silver.
The sol, later called a sou, is the name of a number of different coins, for accounting or payment, dating from Antiquity to today. The name is derived from the late-Roman and Byzantine solidus. Its longevity of use anchored it in many expressions of the French language.
The family of Social War coinage includes all the coins issued by the Italic allies of the Marsic confederation, Marsi, Peligni, Piceni, Vestini, Samnites, Frentani, Marrucini, and Lucani, during the Social War against Rome.
Aizanoi, Latinized as Aezani, was a Phrygian city in western Anatolia. It was located at the site of the modern village of Çavdarhisar, near Kütahya, on both sides of the Penkalas river, c. 1,000 m (3,300 ft) above sea level. The city was an important political and economic centre in Roman times; surviving remains from the period include a well-preserved Temple of Zeus, a combined theatre-stadium complex, and a round building, probably a macellum, inscribed with a copy of the Price Edict of Diocletian. The city fell into decline in Late Antiquity. In 2012 the site was submitted for inclusion on the UNESCO World Heritage List.
The coinage reform of Augustus refers to the reform of Roman currency undertaken by Augustus in 23 BC.
The Carolingian monetary system, also called the Carolingian coinage system or just the Carolingian system, was a currency structure introduced by Charlemagne in the late 8th century as part of a major reform, the effects of which subsequently dominated much of Europe, including Britain, for centuries. It is characterised by having three denominations with values in the ratio 1:12:240, the units of which went under different names in the different languages, but which corresponded to the Latin terms libra (pound), solidus (shilling) and denarius (penny), respectively.
