Coinage Metal
The coinage metals comprise those metallic chemical elements and alloys which have been used to mint coins. Historically, most coinage metals are from the three nonradioactive members of group 11 of the periodic table: copper, silver and gold. Copper is usually augmented with tin or other metals to form bronze. Gold, silver and bronze or copper were the principal coinage metals of the ancient world, the medieval period and into the late modern period when the diversity of coinage metals increased. Coins are often made from more than one metal, either using alloys, coatings ( cladding/plating) or bimetallic configurations. While coins are primarily made from metal, some non-metallic materials have also been used. History Early coinage made from metal came into use during the Axial Age in the Greek world, in northern India, and in China, as coins became a widespread embodiment of money. Bronze, gold, silver and electrum (a naturally occurring pale yellow mixture of gold and ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Group 11 Element
Group 11, by modern IUPAC numbering, is a group (periodic table), group of chemical elements in the periodic table, consisting of copper (Cu), silver (Ag), gold (Au), and roentgenium (Rg), although no chemical experiments have yet been carried out to confirm that roentgenium behaves like the heavier Homologous series, homologue to gold. Group 11, more specifically, the first three members are also known as the ''coinage metals'', due to their usage in minting coins—while the rise in metal prices mean that silver and gold are no longer used for circulating currency, remaining in use for bullion, copper remains a common metal in coins to date, either in the form of copper Cladding (metalworking), clad coinage or as part of the cupronickel alloy. They were most likely the first three elements discovered. Copper, silver, and gold all occur naturally in native element, elemental form. History All three stable elements of the group have been known since prehistoric times, as all of ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Ancient Chinese Coinage
Ancient Chinese coinage includes some of the earliest known coins. These coins, used as early as the Spring and Autumn period (770–476 BCE), took the form of imitations of the cowrie shells that were used in ceremonial exchanges. The same period also saw the introduction of the first metal coins; however, they were not initially round, instead being either knife shaped or spade shaped. Round metal coins with a round, and then later square hole in the center were first introduced around 350 BCE. The beginning of the Qin dynasty (221–206 BCE), the first dynasty to unify China, saw the introduction of a standardised coinage for the whole Empire. Subsequent dynasties produced variations on these round coins throughout the imperial period. At first the distribution of the coinage was limited to use around the capital city district, but by the beginning of the Han dynasty, coins were widely used for such things as paying taxes, salaries and fines.

Ancient Greek
Ancient Greek (, ; ) includes the forms of the Greek language used in ancient Greece and the classical antiquity, ancient world from around 1500 BC to 300 BC. It is often roughly divided into the following periods: Mycenaean Greek (), Greek Dark Ages, Dark Ages (), the Archaic Greece, Archaic or Homeric Greek, Homeric period (), and the Classical Greece, Classical period (). Ancient Greek was the language of Homer and of fifth-century Athens, fifth-century Athenian historians, playwrights, and Ancient Greek philosophy, philosophers. It has contributed many words to English vocabulary and has been a standard subject of study in educational institutions of the Western world since the Renaissance. This article primarily contains information about the Homeric Greek, Epic and Classical periods of the language, which are the best-attested periods and considered most typical of Ancient Greek. From the Hellenistic period (), Ancient Greek was followed by Koine Greek, which is regar ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Siglos
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 (from , , '' shékel'') represented the first bimetallic monetary standard.Michael Alram"DARIC" ''Encyclopaedia Iranica'', December 15, 1994, last updated November 17, 2011 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 (Darics and Sigloi), as well as coins issued by the Achaemenid provincial governors (satraps), such as those stationed in Asia Minor. Early coinage of Western Asia under the Achaemenid Empire When Cyrus the Great (550–530 BC) came to power, coinage was unfamiliar in his realm. Barter, and to some extent silver bullion, was used instead for trade. The practice of using silver bars for currency also seems to have been current in Central Asia from the 6th century. Cyrus th ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Persian Daric
The daric was a gold coin which, along with a similar silver coin, the siglos, represented the bimetallic monetary standard of the Achaemenid Empire.Michael Alram"DARIC" ''Encyclopaedia Iranica'', December 15, 1994, last updated November 17, 2011 Cyrus the Great (550–530 BC) introduced coins to the Persian Empire after 546 BC, following his conquest of Lydia and the defeat of its king Croesus, who had put in place the first coinage in history. It seems Cyrus initially adopted the Lydian coinage as such, and continued to strike Lydia's lion-and-bull coinage. Darius I (521–486 BC) introduced a new thick gold coin which had a standard weight of 8.4 grams, equaling in value 20 silver coins. The gold used in the coins was of very high quality with a purity of 95.83% and it bore the image of the Persian king or a great warrior armed with a bow and arrow. Their use ended with Alexander the Great's invasion in 330 BC, after which they were mostly melted down and recoined as coins ...

Bimetallism
Bimetallism, also known as the bimetallic standard, is a monetary standard in which the value of the monetary unit is defined as equivalent to certain quantities of two metals, typically gold and silver, creating a fixed Exchange rate, rate of exchange between them. For scholarly purposes, "proper" bimetallism is sometimes distinguished as permitting that both gold and silver money are legal tender in unlimited amounts and that gold and silver may be taken to be coined by the Mint (facility), government mints in unlimited quantities. This distinguishes it from "limping standard" bimetallism, where both gold and silver are legal tender but only one is freely coined (e.g. the monies of France, Germany, and the United States after 1873), and from "trade" bimetallism, where both metals are freely coined but only one is legal tender and the other is used as "trade money" (e.g. most monies in western Europe from the 13th to 18th centuries). Economists also distinguish ''legal'' bimeta ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Gold Coin
A gold coin is a coin that is made mostly or entirely of gold. Most gold coins minted since 1800 are 90–92% gold (22fineness#Karat, karat), while most of today's gold bullion coins are pure gold, such as the Britannia (coin), Britannia, Canadian Gold Maple Leaf, Canadian Maple Leaf, and American Buffalo (coin), American Buffalo. Alloyed gold coins, like the American Gold Eagle and South African Krugerrand, are typically 91.7% gold by weight, with the remainder being silver and copper. Until about the 1930s, gold coins were Circulation (currency), circulation coins, including Exonumia, coin-like bracteates and Gold dinar, dinars. Since then, gold coins have mainly been produced as bullion coins for Gold as an investment, investors and as commemorative coins for Coin collecting, collectors. While modern gold coins are still legal tender, they are not used in everyday financial transactions, as the metal value invariably exceeds the Real versus nominal value (economics), nominal ...

Croeseid
The Croeseid, anciently ''Kroiseioi stateres'', was a type of coin, either in gold or silver, which was minted in Sardis by the king of Lydia Croesus (561–546 Before Christ, BC) from around 550 BC. Croesus is credited with issuing the first true gold coins with a standardised purity for general circulation, and the world's first bimetallism, bimetallic monetary system. Precedents Before Croesus, his father Alyattes of Lydia, Alyattes had already started to mint various types of non-standardized coins. They were made in a naturally occurring material called electrum, a variable mix of gold and silver (with about 54% gold and 44% silver), and were in use in Lydia, its capital city Sardis and surrounding areas for about 80 years before Croesus' reign as King of Lydia. The unpredictability of electrum coins' composition implied that they had a variable value, which greatly hampered the development of standardised coinage. The royal symbol stamped on the coin, similar to a seal, was ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
History Of The Rupee
The history of the rupee traces back to ancient times in the Indian subcontinent. The mention of ''rūpya'' by Pāṇini is seemingly the earliest reference in a text about coins. The term in Indian subcontinent was used for referring to a coin. The word "rupee" is derived from a Sanskrit word "rūpya", which means "wrought silver", and maybe also something stamped with an image or a coin. As an adjective it means "shapely", with a more specific meaning of "stamped, impressed", whence "coin". It is derived from the noun ''rūpa'' "shape, likeness, image". ''Arthashastra'', written by Chanakya, prime minister to the first Maurya emperor Chandragupta Maurya (c. 340–290 BC), mentions silver coins as ''rūpyarūpa'', other types including gold coins (suvarṇarūpa), copper coins (tāmrarūpa) and lead coins (sīsarūpa) are mentioned his claim is disputed Rūpa means form or shape, example, rūpyarūpa, rūpya – wrought silver, rūpa – form.

Ancient India
Anatomically modern humans first arrived on the Indian subcontinent between 73,000 and 55,000 years ago. The earliest known human remains in South Asia date to 30,000 years ago. Sedentism, Sedentariness began in South Asia around 7000 BCE; by 4500 BCE, settled life had spread, and gradually evolved into the Indus Valley Civilisation, one of three early Cradle of civilization, cradles of civilisation in the Old World, which flourished between 2500 BCE and 1900 BCE in present-day Pakistan and north-western India. Early in the second millennium BCE, 4.2 kiloyear event, persistent drought caused the population of the Indus Valley to scatter from large urban centres to villages. Rigvedic tribes, Indo-Aryan tribes moved into the Punjab from Central Asia in several Indo-Aryan migration theory, waves of migration.

Lydia
Lydia (; ) was an Iron Age Monarchy, kingdom situated in western Anatolia, in modern-day Turkey. Later, it became an important province of the Achaemenid Empire and then the Roman Empire. Its capital was Sardis. At some point before 800 BC, the Lydian people achieved some sort of political cohesion, and existed as an independent kingdom by the 600s BC. At its greatest extent, during the 7th century BC, it covered all of western Anatolia. In 546 BC, it became a Lydia (satrapy), satrapy of the Achaemenid Empire, known as ''Sparda'' in Old Persian. In 133 BC, it became part of the Roman Republic, Roman Asia (Roman province), province of Asia. Lydian coins, made of electrum, are among the oldest in existence, dated to around the 7th century BC.

Ephesus
Ephesus (; ; ; may ultimately derive from ) was an Ancient Greece, ancient Greek city on the coast of Ionia, in present-day Selçuk in İzmir Province, Turkey. It was built in the 10th century BC on the site of Apasa, the former Arzawan capital, by Attica, Attic and Ionians, Ionian Greek colonists. During the Classical Greece, Classical Greek era, it was one of twelve cities that were members of the Ionian League. The city came under the control of the Roman Republic in 129 BC. The city was famous in its day for the nearby Temple of Artemis (completed around 550 BC), which has been designated one of the Seven Wonders of the Ancient World. Its many monumental buildings included the Library of Celsus and a theatre capable of holding 24,000 spectators. Ephesus was a recipient city of one of the Pauline epistles and one of the seven churches of Asia addressed in the Book of Revelation.
