Shekel (Akkadian: šiqlu or siqlu; Hebrew: שקל, pl. shekels or sheqalim) is any of several ancient units of weight or of currency. Since it was a coin that represented a claim on a weight of barley held in the city warehouse, the term "shekel" was likely used in both contexts: 1) As the name of the coin, and; 2) To describe the measure of barley. This coin weighed about 180 grains (11 grams or .35 troy ounces).
The Sumerian word shekel derives from “She” which meant wheat, and, “Kel” was a measurement similar to a bushel, hence this coin was a symbol of a value of one bushel of wheat. The Hebrew word shekel is based on the Sumerian verbal root for "weighing" (ŠQL), cognate to the Akkadian šiqlu or siqlu, a unit of weight equivalent to the Sumerian gin2. Use of the word was first attested in c. 2150 BC during the Akkadian Empire under the reign of Naram-Sin, and later in c. 1700 BC in the Code of Hammurabi. The ŠQL root is found in the Hebrew words for "to weigh" (shaqal), "weight" (mishqal) and "consideration" (shiqqul), and is related to the TQL root in Aramaic and the ΘQL root in Arabic, such as the words thiqal (the weight) or Mithqal (unit of weight). The famous writing on the wall in the Biblical Book of Daniel includes a cryptic use of the word in Aramaic: "Mene, mene, teqel, u-farsin". The word "shekel" came into the English language via the Hebrew Bible, where it is first used in the Book of Genesis.
The earliest shekels were a unit of weight, used as other units such as grams and troy ounces for trading before the advent of coins. The shekel was common among western Semitic peoples. Moabites, Edomites, and Phoenicians used the shekel, although proper coinage developed very late. Carthaginian coinage was based on the shekel and may have preceded its home town of Tyre in issuing proper coins.
Coins were used and may have been invented by the early Anatolian traders who stamped their marks to avoid weighing each time used. Herodotus states that the first coinage was issued by Croesus, King of Lydia, spreading to the golden Daric (worth 20 sigloi or shekel), issued by the Persian Empire and the silver Athenian obol and drachma. Early coins were money stamped with an official seal to certify their weight. Silver ingots, some with markings were issued. Later authorities decided who designed coins.
As with many ancient units, the shekel had a variety of values depending on era, government and region; weights between 7 and 17 grams and values of 11, 14, and 17 grams are common. When used to pay laborers, recorded wages in the ancient world range widely. The Code of Hammurabi (circa 1800 BC) sets the value of unskilled labor at approximately ten shekels per year of work. Later, records within the Persian Empire (539-333 BC) give ranges from a minimum of two shekels per month for unskilled labor, to as high as seven to ten shekels per month in some records. A survival wage for an urban household during the Persian period would require at least 22 shekels of income per year.
Exodus 30:24 notes that the measures of the ingredients for the holy anointing oil were to be calculated using the Shekel of the Sanctuary (see also Exodus 38:24–26, and similarly at Numbers 3:47 for payment for the redemption of 273 first-born males  and at Numbers 7:12–88 for the offerings of the leaders of the tribes of Israel), suggesting that there were other common measures of shekel in use, or at least that the Temple authorities defined a standard for the shekel to be used for Temple purposes.
The Aramaic tekel, similar to the Hebrew shekel, used in the writing on the wall during the feast of Belshazzar according to the Book of Daniel and defined as weighed, shares a common root with the word shekel and may even additionally attest to its original usage as a weight.
Second Temple period half-Shekel Temple tax
During the Second Temple period, it was customary among Jews to annually offer the half-Shekel into the Temple treasury, for the upkeep and maintenance of the Temple precincts, as also used in purchasing public animal-offerings. This practice not only applied to Jews living in the Land of Israel, but also to Jews living outside the Land of Israel. Archaeological excavations conducted at Horvat 'Ethry in Israel from 1999 to 2001 by Boaz Zissu and Amir Ganor of the Israeli Antiquities Authority (IAA) have yielded important finds, the most-prized of which being a half-Shekel coin minted in the 2nd century CE, upon which are embossed the words "Half-Shekel" in paleo-Hebrew (Hebrew: חצי השקל), and which same coin possesses a silver content of 6.87 grams. According to the Jewish historian, Josephus, the annual monetary tribute of the half-Shekel to the Temple at Jerusalem was equivalent to two Athenian drachmæ, each Athenian or Attic drachma weighing a little over 4.3 grams.
First and Second Jewish Revolt
The Carthaginian or Punic shekel was typically around 7.2 grams in silver and 7.5 grams in gold (suggesting an exchange rate of 12:1). They were apparently first developed on Sicily during the mid-4th century BC. They were particularly associated with the payment of Carthage's mercenary armies and were repeatedly debased over the course of each of the Punic Wars, although the Carthaginian Empire's expansion into Spain under the Barcids before the Second and recovery under Hannibal before the Third permitted improving the amount and quality of the currency. Throughout, it was more common for Carthage's holdings in North Africa to employ bronze or no coinage except when paying mercenary armies and for most of the specie to circulate in Spain, Sardinia, and Sicily.
The Tyrian shekel began to be issued c. 300 BC. Owing to the relative purity of their silver, they were the preferred medium of payment for the Temple tax in Jerusalem despite their royal and pagan imagery. The money changers assaulted by Jesus in the New Testament are those who exchanged worshippers' baser common currency for such shekels and they have been suggested as a possible coin used as the "30 pieces of silver" in the New Testament.
The Israeli shekel (properly sheqel) replaced the Israeli lira or pound in 1980. Its currency sign was ⟨⟩, although it was more commonly denominated as S or IS. It was subdivided into 100 new agoras or agorot. It suffered from hyperinflation and was quickly replaced.
The new shekel replaced it in 1985. Its currency sign is ⟨ ₪ ⟩, although it is often denominated as S or NS. It is subdivided into 100 agoras or agorot. Both Israeli shekels are purely units of currency and not weight. With the 2014 series of notes, the Bank of Israel abandoned the transcriptions Sheqel and Sheqalim in favor of the standard English forms Shekel and Shekels.
