Silver Coin
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. As with all collectible coins, many factors determine the value of a silver coin, such as its rarity, demand, condition and the number originally minted. Ancient silver coins coveted by collectors include the Denarius and Miliarense, while more recent collectible silver coins include the Morgan Dollar and the Spanish Milled Dollar. Other than collector's silver coins, silver bullion coins are popular among people who desire a " hedge" against currency inflation or store of value. Silver has an international currency symbol of XAG under ISO 4217.

1 Ecu Louis XVI 1- 1784 M
1 (one, unit, unity) is a number, numeral, and glyph. It is the first and smallest positive integer of the infinite sequence of natural numbers. This fundamental property has led to its unique uses in other fields, ranging from science to sports, where it commonly denotes the first, leading, or top thing in a group. 1 is the unit of counting or measurement, a determiner for singular nouns, and a gender-neutral pronoun. Historically, the representation of 1 evolved from ancient Sumerian and Babylonian symbols to the modern Arabic numeral. In mathematics, 1 is the multiplicative identity, meaning that any number multiplied by 1 equals the same number. 1 is by convention not considered a prime number. In digital technology, 1 represents the "on" state in binary code, the foundation of computing. Philosophically, 1 symbolizes the ultimate reality or source of existence in various traditions. In mathematics The number 1 is the first natural number after 0. Each natural number ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Currency
A currency is a standardization of money in any form, in use or circulation as a medium of exchange, for example banknotes and coins. A more general definition is that a currency is a ''system of money'' in common use within a specific environment over time, especially for people in a nation state. Under this definition, the British Pound sterling (£), euros (€), Japanese yen (¥), and U.S. dollars (US$) are examples of (government-issued) fiat currencies. Currencies may act as stores of value and be traded between nations in foreign exchange markets, which determine the relative values of the different currencies. Currencies in this sense are either chosen by users or decreed by governments, and each type has limited boundaries of acceptance; i.e., legal tender laws may require a particular unit of account for payments to government agencies. Other definitions of the term ''currency'' appear in the respective synonymous articles: banknote, coin, and money. Th ... [...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 China
The history of China spans several millennia across a wide geographical area. Each region now considered part of the Chinese world has experienced periods of unity, fracture, prosperity, and strife. Chinese civilization first emerged in the Yellow River valley, which along with the Yangtze River, Yangtze basin constitutes the geographic core of the Sinosphere, Chinese cultural sphere. China maintains a rich diversity of ethnic and linguistic people groups. The Chinese historiography, traditional lens for viewing Chinese history is the Dynasties of China, dynastic cycle: imperial dynasties rise and fall, and are ascribed certain achievements. This lens also tends to assume Chinese civilization can be traced as an unbroken thread Five thousand years of Chinese civilization, many thousands of years into the past, making it one of the Cradle of civilization, cradles of civilization. At various times, states representative of a dominant Chinese culture have directly controlled areas ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Obolus
The obol (, ''obolos'', also ὀβελός (''obelós''), ὀβελλός (''obellós''), ὀδελός (''odelós''). "nail, metal spit"; ) was a form of ancient Greek currency and weight. Currency Obols were used from early times. According to Plutarch they were originally spits of copper or bronze traded by weight, while six obols make a drachma or a handful, since that was as many as the hand could grasp. Heraklides of Pontus (died 310 BC) is cited as having mentioned the obols of Heraion and also gives the etymology of ''obolos'' (the name of the coin) from ''obelos'' (the word for "spit, spike, nail"). Similarly, the historian Ephorus in his equally lost work ''On Inventions'' (mid 4th century BC) is said to have mentioned the obols of Heraion. Excavations at Argos discovered several dozen of these early obols, dated well before 800 BC; they are now displayed at the Numismatic Museum of Athens. Archaeologists today describe the iron spits as "utensil- ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Stater
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. History The stater, as a Greek silver currency, first as ingots, and later as coins, circulated from the 8th century BC to AD 50. The earliest known stamped stater (having the mark of some authority in the form of a picture or words) is an electrum turtle coin, struck at Aegina that dates to about 650 BC. It is on display at the Bibliothèque Nationale in Paris. According to Robin Lane Fox, the stater as a weight unit was borrowed by the Euboean stater weighing from the Phoenician shekel, which had about the same weight as a stater () and was also one fiftieth of a mina.Lane Fox, Robin.

Mediterranean Sea
The Mediterranean Sea ( ) is a sea connected to the Atlantic Ocean, surrounded by the Mediterranean basin and almost completely enclosed by land: on the east by the Levant in West Asia, on the north by Anatolia in West Asia and Southern Europe, on the south by North Africa, and on the west almost by the Morocco–Spain border. The Mediterranean Sea covers an area of about , representing 0.7% of the global ocean surface, but its connection to the Atlantic via the Strait of Gibraltar—the narrow strait that connects the Atlantic Ocean to the Mediterranean Sea and separates the Iberian Peninsula in Europe from Morocco in Africa—is only wide. Geological evidence indicates that around 5.9 million years ago, the Mediterranean was cut off from the Atlantic and was partly or completely desiccation, desiccated over a period of some 600,000 years during the Messinian salinity crisis before being refilled by the Zanclean flood about 5.3 million years ago. The sea was an important ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Colonies
A colony is a territory subject to a form of foreign rule, which rules the territory and its indigenous peoples separated from the foreign rulers, the colonizer, and their '' metropole'' (or "mother country"). This separated rule was often organized into colonial empires, with their metropoles at their centers, making colonies neither annexed or even integrated territories, nor client states. Particularly new imperialism and its colonialism advanced this separated rule and its lasting coloniality. Colonies were most often set up and colonized for exploitation and possibly settlement by colonists. The term colony originates from the ancient Roman , a type of Roman settlement. Derived from ''colonus'' (farmer, cultivator, planter, or settler), it carries with it the sense of 'farm' and 'landed estate'. Furthermore, the term was used to refer to the older Greek ''apoikia'' (), which were overseas settlements by ancient Greek city-states. The city that founded such a settlem ...

Aegina
Aegina (; ; ) is one of the Saronic Islands of Greece in the Saronic Gulf, from Athens. Tradition derives the name from Aegina (mythology), Aegina, the mother of the mythological hero Aeacus, who was born on the island and became its king. Administration Municipality The municipality of Aegina consists of the island of Aegina and a few offshore islets. It is part of the Islands (regional unit), Islands regional unit, Attica (region), Attica region.

The buildings of the island are examples of Neoclassical architecture with a strong folk element, bu ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Alloy
An alloy is a mixture of chemical elements of which in most cases at least one is a metal, metallic element, although it is also sometimes used for mixtures of elements; herein only metallic alloys are described. Metallic alloys often have properties that differ from those of the pure elements from which they are made. The vast majority of metals used for commercial purposes are alloyed to improve their properties or behavior, such as increased strength, hardness or corrosion resistance. Metals may also be alloyed to reduce their overall cost, for instance alloys of gold and Copper(II) sulfate, copper. A typical example of an alloy is SAE 304 stainless steel, 304 grade stainless steel which is commonly used for kitchen utensils, pans, knives and forks. Sometime also known as 18/8, it as an alloy consisting broadly of 74% iron, 18% chromium and 8% nickel. The chromium and nickel alloying elements add strength and hardness to the majority iron element, but their main function is ...

Electrum
Electrum is a naturally occurring alloy of gold and silver, with trace amounts of copper and other metals. Its color ranges from pale to bright yellow, depending on the proportions of gold and silver. It has been produced artificially and is also known as "Colored gold#Green gold, green gold".Emsley, John (2003Nature's building blocks: an A–Z guide to the elements Oxford University Press. p. 168. . Electrum was used as early as the third millennium BC in the Old Kingdom of Egypt, sometimes as an exterior coating to the pyramidion, pyramidia atop ancient Egyptian pyramids and obelisks. It was also used in the making of ancient Beaker (archaeology) , drinking vessels. The first known metal coins made were of electrum, dating back to the end of the 7th century or the beginning of the 6th century BC. Etymology The name ''electrum'' is the Latinized form of the Greek language, Greek word ἤλεκτρον (''ḗlektron''), mentioned in the ''Odyssey'', referring to a metallic s ...

Anatolia
Anatolia (), also known as Asia Minor, is a peninsula in West Asia that makes up the majority of the land area of Turkey. It is the westernmost protrusion of Asia and is geographically bounded by the Mediterranean Sea to the south, the Aegean Sea to the west, the Turkish Straits to the northwest, and the Black Sea to the north. The eastern and southeastern limits have been expanded either to the entirety of Asiatic Turkey or to an imprecise line from the Black Sea to the Gulf of Alexandretta. Topographically, the Sea of Marmara connects the Black Sea with the Aegean Sea through the Bosporus and the Dardanelles, and separates Anatolia from Thrace in Southeast Europe. During the Neolithic, Anatolia was an early centre for the development of farming after it originated in the adjacent Fertile Crescent. Beginning around 9,000 years ago, there was a major migration of Anatolian Neolithic Farmers into Neolithic Europe, Europe, with their descendants coming to dominate the continent a ...
