Electrum in the context of "Shekel"

Alyattes (Lydian language: 𐤥𐤠𐤩𐤥𐤤𐤯𐤤𐤮 Walweteś; Ancient Greek: Ἀλυάττης Aluáttēs; reigned c. 635 – c. 585 BC), sometimes described as Alyattes I, was the fourth king of the Mermnad dynasty in Lydia, the son of Sadyattes, grandson of Ardys, and great-grandson of Gyges. He died after a reign of 57 years and was succeeded by his son Croesus.

Alyattes was the first monarch who issued coins, made from electrum (and his successor Croesus was the first to issue gold coins). Alyattes is therefore sometimes mentioned as the originator of coinage, or of currency.

Gold is a chemical element; it has chemical symbol Au (from Latin aurum) and atomic number 79. In its pure form, it is a bright-metallic-yellow, dense, soft, malleable, and ductile metal. Chemically, gold is a transition metal, a group 11 element, and one of the noble metals. It is one of the least reactive chemical elements, being the second lowest in the reactivity series, with only platinum ranked as less reactive. Gold is solid under standard conditions.

Gold often occurs as the free element (native state), as nuggets or grains, in rocks, veins, and alluvial deposits. It occurs in a solid solution series with the native element silver (as in electrum), naturally alloyed with other metals like copper and palladium, and mineral inclusions such as within pyrite. Less commonly, it occurs in minerals as gold compounds, often with tellurium (gold tellurides).

Histiaeus (Ancient Greek: Ἱστιαῖος, died 493 BC), the son of Lysagoras, was a Greek ruler of Miletus in the late 6th century BC. Histiaeus was tyrant of Miletus under Darius I, king of Persia, who had subjugated Miletus and the other Ionian states in Asia Minor, and who generally appointed Greeks as tyrants to rule the Greek cities of Ionia in his territory.

A pyramidion (plural: pyramidia) is the capstone of an Egyptian pyramid or the upper section of an obelisk. Speakers of the Ancient Egyptian language referred to pyramidia as benbenet and associated the pyramid as a whole with the sacred benben stone.

Pyramidia were usually made of limestone, sandstone, basalt or granite, and were sometimes covered with plates of copper, gold or electrum. From the Middle Kingdom onward, they were often "inscribed with royal titles and religious symbols".

A native metal is any metal that is found pure in its metallic form in nature. Metals that can be found as native deposits singly or in alloys include antimony, arsenic, bismuth, cadmium, chromium, cobalt, indium, iron, manganese, molybdenum, nickel, niobium, rhenium, tantalum, tellurium, tin, titanium, tungsten, vanadium, and zinc, as well as the gold group (gold, copper, lead, aluminium, mercury, silver) and the platinum group (platinum, iridium, osmium, palladium, rhodium, ruthenium). Among the alloys found in native state have been brass, bronze, pewter, German silver, osmiridium, electrum, white gold, silver-mercury amalgam, and gold-mercury amalgam.

Only gold, silver, copper and the platinum group occur native in large amounts. Over geological time scales, very few metals can resist natural weathering processes like oxidation, so mainly the less reactive metals such as gold and platinum are found as native metals. The others usually occur as isolated pockets where a natural chemical process reduces a common compound or ore of the metal, leaving the pure metal behind as small flakes or inclusions.

The Nobel Prizes are awards administered by the Nobel Foundation and granted in accordance with the principle of "for the greatest benefit to humankind". The prizes were first awarded in 1901, marking the fifth anniversary of Alfred Nobel's death. The original Nobel Prizes covered five fields: physics, chemistry, physiology or medicine, literature, and peace, specified in Nobel's will. A sixth prize, the Prize in Economic Sciences, was established in 1968 by Sveriges Riksbank (Sweden's central bank) in memory of Alfred Nobel. The Nobel Prizes are widely regarded as the most prestigious awards available in their respective fields.

Except in extraordinary circumstances, such as war, all six prizes are given annually. Each recipient, known as a laureate, receives a green gold medal plated with 24 karat gold, a diploma, and a monetary award. As of 2023, the Nobel Prize monetary award is 11,000,000 kr, equivalent to approximately US$1,035,000. The medal shows Nobel in profile with "NAT. MDCCCXXXIII-OB. MDCCCXCVI" which is his year of birth, 1833 (NAT) and year of death, 1896 (OB). No more than three individuals may share a prize, although the Nobel Peace Prize can be awarded to organisations of more than three people. Nobel Prizes are not awarded posthumously, but if a person is awarded a prize and dies before receiving it, the prize is presented.

In the Middle Ages, the term bezant (Old French: besant, from Latin bizantius aureus) was used in Western Europe to describe several gold coins of the east, all derived ultimately from the Roman solidus. The word itself comes from the Greek Byzantion, the ancient name of Constantinople, the capital of the Byzantine Empire.

The original "bezants" were the gold coins produced by the government of the Byzantine Empire, first the nomisma and from the 11th century the hyperpyron. Later, the term was used to cover the gold dinars produced by Islamic governments. In turn, the gold coins minted in the Kingdom of Jerusalem and County of Tripoli were termed "Saracen bezants" (besantius saracenatus), or "fake dinars" (dīnār ṣūrī), since they were modelled on the Fatimid dinar. A completely different electrum coin based on Byzantine trachea was minted in the Kingdom of Cyprus and called the "white bezant".
