A coin is a small object, usually round and flat, used primarily as a medium of exchange or legal tender. They are standardized in weight, and produced in large quantities at a mint in order to facilitate trade. They are most often issued by a government. Coins often have images, numerals, or text on them. Obverse and its opposite, reverse, refer to the two flat faces of coins and medals. In this usage, obverse means the front face of the object and reverse means the back face. The obverse of a coin is commonly called heads, because it often depicts the head of a prominent person, and the reverse is known as tails.
Commemorative coins are coins issued to commemorate some particular event or issue with a distinct design with reference to the occasion on which they were issued. Many coins of this category serve as collectors items only, although some countries also issue commemorative coins for regular circulation.
The history of ancient Greek coinage can be divided into four periods: the Archaic, the Classical, the Hellenistic and the Roman. The Archaic period extends from the introduction of coinage to the Greek world during the 7th century BC until the Persian Wars in about 480 BC. The Classical period then began, and lasted until the conquests of Alexander the Great in about 330 BC, which began the Hellenistic period, extending until the Roman absorption of the Greek world in the 1st century BC. The Greek cities continued to produce their own coins for several more centuries under Roman rule. The coins produced during this period are called Roman provincial coins or Greek Imperial Coins.
Exonumia are numismatic items other than coins and paper money. This includes "Good For" tokens, badges, counterstamped coins, elongated coins, encased coins, souvenir medallions, tags, wooden nickels and other similar items. It is related to numismatics, and many coin collectors are also exonumists.
Roman Republican currency refers to 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 merk is a long-obsolete Scottish silver coin. Originally the same word as a money mark of silver, the merk was in circulation at the end of the 16th century and in the 17th century. It was originally valued at 13 shillings 4 pence, later raised to 14s. Scots.
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 American twenty-cent piece is a coin struck from 1875 to 1878, but only for collectors in the final two years. Proposed by Nevada Senator John P. Jones, it proved a failure due to confusion with the quarter, to which it was close in both size and value.
Sir Edward Rossiter, 1 January 1618 to 9 January 1669, was an English landowner, soldier and politician from Lincolnshire. He fought with the Parliamentarian army in the Wars of the Three Kingdoms and sat as an MP at various times between 1646 and 1660.
The coins of Lundy are unofficial issues of currency from the island of Lundy, in the Bristol Channel off the west coast of England. Two bronze coins, the "half puffin" and "one puffin", were issued with a 1929 date and featured a portrait of Martin Coles Harman who owned the island and was responsible for the issue. The coins were struck again with slightly modified designs and updated dates in 1965, 1977, and 2011, as commemorative tokens not intended for circulation.
The Achaemenid Empire issued coins from 520 BC–450 BC to 330 BC. The Persian daric was the first gold coin which, along with a similar silver coin, the siglos represented the first bimetallic monetary standard. It seems that before the Persians issued their own coinage, a continuation of Lydian coinage under Persian rule is likely. Achaemenid coinage includes the official imperial issues, as well as coins issued by the Achaemenid provincial governors (satraps), such as those stationed in Asia Minor.
Civil War tokens are token coins that were privately minted and distributed in the United States between 1861 and 1864. They were used mainly in the Northeast and Midwest. The widespread use of the tokens was a result of the scarcity of government-issued cents during the Civil War.
The history of the English penny can be traced back to the Anglo-Saxon kingdoms of the 7th century: to the small, thick silver coins known to contemporaries as pæningas or denarii, though now often referred to as sceattas by numismatists. Broader, thinner pennies inscribed with the name of the king were introduced to Southern England in the middle of the 8th century. Coins of this format remained the foundation of the English currency until the 14th century.
The term tiền is used to refer to various currency-related concepts used in Vietnamese history. The name is a cognate with the Chinese qián (錢), a unit of weight called "mace" in English. It can refer to a unit of weight used in precious metal coinages as well as the number of cash coins in a string. The name was also used for different awards, both Chinese-style and Western-style awards given in Vietnam throughout different times of its history.
The British pre-decimal penny was a denomination of sterling coinage worth 1⁄240 of one pound or 1⁄12 of one shilling. Its symbol was d, from the Roman denarius. It was a continuation of the earlier English penny, and in Scotland it had the same monetary value as one pre-1707 Scottish shilling. The penny was originally minted in silver, but from the late 18th century it was minted in copper, and then after 1860 in bronze.
Viking coinage was used during the Viking Age of northern Europe. Prior to the usage and minting of coins, the Viking economy was predominantly a bullion economy, where the weight and size of a particular metal is used as a method of evaluating value, as opposed to the value being determined by the specific type of coin. By the ninth century, the Viking raids brought them into contact with cultures well familiarised with the use of coins in economies of Europe, hence influencing the Vikings own production of coins.
Siege money or money of necessity was minted in Newark-on-Trent in 1646 during the third and final siege (1645–1646) — the last year of the First English Civil War. To meet need for money, the besieged Royalists set up a mint that manufactured lozenge-shaped coins — half-crowns, shillings, ninepences, and sixpences.
Peroz, was according to modern scholarship an early Kidarite ruler in Gandhara, right after the end of Kushano-Sasanians.
The one sen coin (一銭) was a Japanese coin worth one-hundredth of a Japanese yen, as 100 sen equalled 1 yen. One sen coins were first struck for circulation during the 6th year of Meiji's reign (1873) using a dragon design. The denomination had been adopted in 1871 but coinage at the time could not be carried out. Aside from an alloy change and a new rice stalk wreath design, one sen coins remained the same weight and size for the remainder of the era. The situation changed when World War I broke out under Emperor Taishō as rising metal costs led to a size and weight reduction. These smaller coins were first produced in 1916 with a paulownia design which was seen as liberal at the time. Emperor Shōwa took the throne in 1926, and Japan was pushed into a militaristic regime by the early 1930s causing metals to be set aside for wartime conditions. These effects would later impact one sen coins through numerous alloy, size, and design changes.
Sasanian coinage was produced within the domains of the Iranian Sasanian Empire (224–651). Together with the Roman Empire, the Sasanian Empire was the most important money-issuing polity in Late Antiquity. Sasanian coinage had a significant influence on coinage of other polities. Sasanian coins are a pivotal primary source for the study of the Sasanian period, and of major importance in history and art history in general. The Sylloge nummorum Sasanidarum is the most important primary work of reference for Sasanian coins.
