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).
The two guinea piece was a gold coin first minted in England in 1664 with a face value of forty shillings. The source of the gold used, also provided the coin its name - the "guinea", with the regular addition of an elephant or castle symbol on the earliest issues to denote bullion supplied by the Royal African Company. For most of its period of production, the coin weighed between 16.7 and 16.8 grams and was 31-32 millimetres in diameter, although the earliest coins of Charles II were about 0.1 grams lighter and 1 millimetre smaller.
Shekel or sheqel is an ancient Mesopotamian coin, usually of silver. A shekel was first a unit of weight—very roughly 11 grams —and became currency in ancient Tyre, Carthage and Hasmonean Judea.
The as, occasionally assarius, was a bronze, and later copper, coin used during the Roman Republic and Roman Empire.
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 quadrigatus was a medium-sized silver coin produced by the Roman Republic during the 3rd century BC. The obverse featured a young janiform bust and the reverse featured Victory driving a quadriga, giving the coin its Roman name, with the inscription "ROMA" below.
The semis was a small Roman bronze coin that was valued at half an as. During the Roman Republic, the semis was distinguished by an 'S' or 6 dots. Some of the coins featured a bust of Saturn on the obverse, and the prow of a ship on the reverse.
The quadrans or teruncius was a low-value Roman bronze coin worth one quarter of an as. The quadrans was issued from the beginning of cast bronze coins during the Roman Republic, showing three pellets representing three unciae as a mark of value. The obverse type, after some early variations, featured the bust of Hercules, while the reverse featured the prow of a galley. Coins with the same value were issued from other cities in Central Italy, using a cast process.
The bes was an Ancient Roman bronze coin produced during the Roman Republic. Valued at two thirds of an as, it was only produced in 126 BC by C. Cassius in combination with the dodrans, another very rare denomination which was valued at three quarters of an as. The obverse head displayed the god Liber facing to the right.
The triens was an Ancient Roman bronze coin produced during the Roman Republic valued at one-third of an as. The most common design for the triens featured the bust of Minerva and four pellets on the obverse and the prow of a galley on the reverse. It was not a common denomination and was last struck c. 89 BC.
The uncia was a Roman currency worth one twelfth of an as.
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 ducat coin was used as a trade coin in Europe from the later Middle Ages to the 19th century. Its most familiar version, the gold ducat or sequin containing around 3.5 grams of 98.6% fine gold, originated in Venice in 1284 and gained wide international acceptance over the centuries. Similarly named silver ducatons also existed. The gold ducat circulated along with the Florentine florin and preceded both the modern British pound sterling and the United States dollar.
The Coinage of India began anywhere between early 1st millennium BCE to the 6th century BCE, and consisted mainly of copper and silver coins in its initial stage. The coins of this period were Karshapanas or Pana. A variety of earliest Indian coins, however, unlike those circulated in West Asia, were stamped bars of metal, suggesting that the innovation of stamped currency was added to a pre-existing form of token currency which had already been present in the Janapadas and Mahajanapada kingdoms of the Early historic India. The kingdoms that minted their own coins included Gandhara, Kuntala, Kuru, Magadha, Panchala, Shakya, Surasena, Surashtra and Vidarbha etc.
The stater was an ancient coin used in various regions of Greece. The term is also used for similar coins, imitating Greek staters, minted elsewhere in ancient Europe.
Aksumite currency was coinage produced and used within the Kingdom of Aksum centered in present-day Eritrea and Ethiopia. Its mintages were issued and circulated from the reign of King Endubis around AD 270 until it began its decline in the first half of the 7th century where they started using Dinar along with most parts of the Middle East. During the succeeding medieval period, Mogadishu currency, minted by the Sultanate of Mogadishu, was the most widely circulated currency in the eastern and southern parts of the Horn of Africa from the start of the 12th century.
Aes grave is a term in numismatics indicating bronze cast coins used in central Italy during the 3rd century BC, whose value was generally indicated by signs: I for the as, S for semis and pellets for unciae. Standard weights for the as were 272, 327, or 341 grams, depending upon the issuing authority.
Like the Egyptians, Phoenicians and Carthaginians, the Etruscans were rather slow to adopt the invention of coinage. The brief period of Etruscan coinage, with the predominance of marks of value, seems to be an amalgam that reconciles two very different monetary systems: the 'primitive' bronze-weighing and aes grave economy of central Italy with that of struck silver and gold issues of southern Italian Greek type not familiar in Etruria.
The coinage of Capua concerns coins minted in ancient Capua, a city in ancient Campania, corresponding to present-day Santa Maria Capua Vetere. The city was located on the Appian Way and was the most important in the area, probably the largest center in the Italian peninsula after Rome.
