The Napoléon is the colloquial term for a former French gold coin. The coins were minted in denominations of 5, 10, 20, 40, 50, and 100 francs. This article focuses on the 20 franc coins issued during the reign of Napoléon Bonaparte, which are 21 mm in diameter, weigh 6.45 grams and, at 90% pure, contain 0.1867 troy ounces (5.807 g) of pure gold. The coin was issued during the reign of Napoleon I and features his portrait on the obverse. The denomination continued in use through the 19th century and later French gold coins in the same denomination were generally referred to as "Napoléons". Earlier French gold coins are referred to as Louis or écu. Gold Napoléons have historically proven more resilient than other gold coins to economic forces, such as after the Suez crisis when unlike other coins Napoléons did not weaken.
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 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.
The dime, in United States usage, is a ten-cent coin, one tenth of a United States dollar, labeled formally as "one dime". The denomination was first authorized by the Coinage Act of 1792.
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.
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.
Apollodotus I, known in Indian sources as Apaladata, was an Indo-Greek king from 180 BC to 160 BC, or between 174 and 165 BC who ruled the western and southern parts of the Indo-Greek kingdom, from Taxila in the Punjab region to the areas of Sindh and possibly Gujarat.
Dionysius Soter was an Indo-Greek king in the area of eastern Punjab.
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.
Bolskan was an Iberian city located in the territory of the Vescetani in north-eastern Spain about 65 km north of the Ebro River. It was on the site that is now occupied by the city of Huesca, in the Iberian Peninsula.
Illyrian coinage which began in the 6th century BC continued up to the 1st century of Roman rule. It was the southern Illyrians who minted the first coins followed by the northern Illyrian during the Roman era. Illyrian coins have also been found in other areas apart from Illyria, such ancient Macedonia, Italy, Greece, Asia Minor and Egypt.
Carthaginian or Punic currency refers to the coins of ancient Carthage, a Phoenician city-state located near present-day Tunis, Tunisia. Between the late fifth century BC and its destruction in 146 BC, Carthage produced a wide range of coinage in gold, electrum, silver, billon, and bronze. The base denomination was the shekel, probably pronounced in Punic. Only a minority of Carthaginian coinage was produced or used in North Africa. Instead, the majority derive from Carthage's holdings in Sardinia and western Sicily.
The Post-Mauryan coinage of Gandhara refers to the period of coinage production in Gandhara, following the breakup of the Maurya Empire. When Mauryan central power disappeared, several small independent entities were formed, which started to strike their own coins, defining a period of Post-Mauryan coinage that ends with the rise of the Gupta Empire in the 4th century CE. This phenomenon was particularly precocious and significant in the area of Gandhara in the northwest, and more particularly in the city of Taxila, in modern-day Pakistan.
Post-Mauryan coinage refers to the period of coinage production in India following the breakup of the Maurya Empire.
Greek coinage of Italy and Sicily originated from local Italiotes and Siceliotes who formed numerous city states. These Hellenistic communities descended from Greek migrants. Southern Italy was so thoroughly hellenized that it was known as the Magna Graecia. Each of the polities struck their own coinage.
The 1 lira cent, commonly called centesimino, was the smallest denomination of Italian lira coins. Like the contemporary 2, 5 and 10 cent coins, it was made of a bronze alloy composed of 960‰ copper and 40‰ tin. The 1-cent coins were minted between 1861 and 1918, only to be withdrawn from circulation in 1924.
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.
The coinage of Cales concerns coins minted in Cales, a city in Campania, the most important urban center of the ancient Italic population of the Ausones. Cales was located on the Via Latina, halfway between the mountains of Samnium and the plains of Campania felix, a few kilometers north of Casilinum and just south of Teanum Sidicinum.
The Lombard coinage of Benevento, part of the more general Lombard coinage, is the set of coins minted between about 680 and the end of the ninth century in the duchy and principality of Benevento. Solidi and tremisses, both gold coins that imitated those of the Eastern Roman Empire, were first minted; later followed the issuance of coins in the names first of the dukes and then of the Benevento princes. Toward the end of the 8th century alongside the gold coins were minted silver coins, which gradually took the place of the earlier ones, as moreover happened in the rest of Western Europe. Silver became the prevalent coinage metal only from the mid-9th century.
The coinage of Adelchis, prince of Benevento, constitutes a special chapter in the Lombard coinage of Benevento and bears witness to the political changes that took place during his principality. The period in which Adelchis minted runs from 854, when he became prince of Benevento, to 878; his coinage is centered on the denier, a silver coinage that became widespread in Europe following Charlemagne's rise to power.
