Saudi Riyal
The Saudi riyal ( ') is the currency of Saudi Arabia. It is officially abbreviated as SAR (Saudi Arabian Riyal), though SR (Saudi Riyal) is also commonly used, It is subdivided into 100 halalas ( '). History The riyal has been the currency of Saudi Arabia since the country came into being and was the currency of Hejaz before Saudi Arabia was created, one of the primary currencies in the Mediterranean region during the Ottoman Arabia, Ottoman era. The Hejaz riyal was based on but not equivalent to the Ottoman 20 Ottoman lira, kuruş coin and was consequently divided into 20 qirsh. However, although the Hejaz riyal was the same weight as the Ottoman 20 kuruş, it was minted in .917 fineness, compared to .830 fineness for the Ottoman coin. Thus, because the first Saudi riyal had the same specifications as the Hejaz riyal and circulated alongside Ottoman coins, it came to be worth 22 Ottoman kuruş and was consequently subdivided into 22 ghirsh when coins denominated in qirsh were is ...

Hejaz Riyal
The riyal (Arabic language, Arabic: ' was the currency of the Kingdom of Hejaz between 1916 and 1925. It was subdivided into 20 qirsh (). The riyal was a silver coin the same weight as the Ottoman 20 Turkish lira, kuruş coin but was minted in .917 fineness rather than .830 fineness. The Hejaz riyal was replaced by the Saudi riyal in 1925 at par. Coins In 1916, bronze coins were issued for , , and 1 qirsh together with silver 5, 10 and 20 qirsh. Gold 1 dinar coins were also minted. Turkish and Egyptian coins and Maria Theresa thaler, were countermarked for use in Hejaz, with the name of the kingdom in .

Sovereign (British Coin)
The sovereign is a British gold coin with a face value, nominal value of one pound sterling (£1) and contains of pure gold. Struck since 1817, it was originally a Currency in circulation, circulating coin that was accepted in Britain and elsewhere in the world; it is now a bullion coin and is sometimes mounted in jewellery. In addition, circulation strikes and proof coin, proof examples are often collected for their numismatic value. In most recent years, it has borne the design of Saint George and the Dragon on the obverse and reverse, reverse; the initials () of the designer, Benedetto Pistrucci, are visible to the right of the date. The coin was named after the English gold sovereign, which was last minted about 1603, and originated as part of the Great Recoinage of 1816. Many in Parliament believed a one-pound coin should be issued rather than the 21-shilling guinea (British coin), guinea that was struck until that time.

Saudi Arabian Monetary Authority
The Saudi Central Bank (), previously known as the Saudi Arabian Monetary Authority (SAMA; ), established in 1952, is the central bank of the Kingdom of Saudi Arabia. Despite the name change in 2020, the Saudi Central Bank has continued to use the same acronym (SAMA). History Prior to the establishment of the Saudi Central Bank, the Saudi Hollandi Bank, a branch of the Netherlands Trading Society from 1926 acted as a de facto central bank. It kept the Kingdom's gold reserves and received oil revenues on behalf of the Saudi Arabian government. In 1928 it assisted in the establishment of a new Saudi silver coin, commissioned by King Abdulaziz which became the Kingdom's first independent currency. The Saudi Hollandia Bank handed over its responsibilities to the SAMA when it was established in 1952 and became a model for other foreign banks in the kingdom. The building's current headquarters, which was built in 1985 was designed by American architect Minoru Yamasaki. The modern cen ...

Cupronickel
Cupronickel or copper–nickel (CuNi) is an alloy of copper with nickel, usually along with small quantities of other metals added for strength, such as iron and manganese. The copper content typically varies from 60 to 90 percent. ( Monel is a nickel–copper alloy that contains a minimum of 52 percent nickel.) Despite its high copper content, cupronickel is silver in colour. Cupronickel is highly resistant to corrosion by salt water, and is therefore used for piping, heat exchangers and condensers in seawater systems, as well as for marine hardware. It is sometimes used for the propellers, propeller shafts, and hulls of high-quality boats. Other uses include military equipment and chemical industry, petrochemical industry, and electrical industries. In decorative use, a cupronickel alloy called nickel silver is common, although it contains additional zinc but no silver. Another common 20th-century use of cupronickel was silver-coloured coins. For this use, the typical alloy ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Brass
Brass is an alloy of copper and zinc, in proportions which can be varied to achieve different colours and mechanical, electrical, acoustic and chemical properties, but copper typically has the larger proportion, generally copper and zinc. In use since prehistoric times, it is a substitutional alloy: atoms of the two constituents may replace each other within the same crystal structure. Brass is similar to bronze, a copper alloy that contains tin instead of zinc. Both bronze and brass may include small proportions of a range of other Chemical element, elements including arsenic, lead, phosphorus, aluminium, manganese and silicon. Historically, the distinction between the two alloys has been less consistent and clear, and increasingly museums use the more general term "list of copper alloys, copper alloy". Brass has long been a popular material for its bright gold-like appearance and is still used for drawer pulls and door handle, doorknobs. It has also been widely used to ma ...

Emblem Of Saudi Arabia
The Emblem of Saudi Arabia () was adopted in 1950. According to the Basic Law of Saudi Arabia, Saudi Basic Law, it consists of two crossed swords with a Date palm, palm tree in the space above and between the blades. The two swords represent the Kingdom of Hejaz and the Sultanate of Nejd, Sultanate of Nejd and its dependencies, which were Kingdom of Hejaz and Nejd, united under Ibn Saud of Saudi Arabia, Ibn Saud in 1926, or strength, stamina, and sacrifice. The crest represents that prosperity can only be had through justice. The palm stands for growth, vitality, and prosperity and the crossed swords represent justice. The palm tree represents the Kingdom's assets which are defined as its Saudi Arabian people, people, Culture of Saudi Arabia, heritage, History of Saudi Arabia, history, and Oil reserves in Saudi Arabia, resources natural and non-natural. Thus, the palm is shown to be guarded by the two swords, which represent the Armed Forces of Saudi Arabia, forces to be used i ...

Steel
Steel is an alloy of iron and carbon that demonstrates improved mechanical properties compared to the pure form of iron. Due to steel's high Young's modulus, elastic modulus, Yield (engineering), yield strength, Fracture, fracture strength and low raw material cost, steel is one of the most commonly manufactured materials in the world. Steel is used in structures (as concrete Rebar, reinforcing rods), in Bridge, bridges, infrastructure, Tool, tools, Ship, ships, Train, trains, Car, cars, Bicycle, bicycles, Machine, machines, Home appliance, electrical appliances, furniture, and Weapon, weapons. Iron is always the main element in steel, but other elements are used to produce various grades of steel demonstrating altered material, mechanical, and microstructural properties. Stainless steels, for example, typically contain 18% chromium and exhibit improved corrosion and Redox, oxidation resistance versus its carbon steel counterpart. Under atmospheric pressures, steels generally ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Nickel
Nickel is a chemical element; it has symbol Ni and atomic number 28. It is a silvery-white lustrous metal with a slight golden tinge. Nickel is a hard and ductile transition metal. Pure nickel is chemically reactive, but large pieces are slow to react with air under standard conditions because a passivation layer of nickel oxide forms on the surface that prevents further corrosion. Even so, pure native nickel is found in Earth's crust only in tiny amounts, usually in ultramafic rocks, and in the interiors of larger nickel–iron meteorites that were not exposed to oxygen when outside Earth's atmosphere. Meteoric nickel is found in combination with iron, a reflection of the origin of those elements as major end products of supernova nucleosynthesis. An iron–nickel mixture is thought to compose Earth's outer and inner cores. Use of nickel (as natural meteoric nickel–iron alloy) has been traced as far back as 3500 BCE. Nickel was first isolated and classifie ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Anno Hegirae
The Hijri year () or era () is the era used in the Islamic lunar calendar. It begins its count from the Islamic New Year in which Muhammad and his followers migrated from Mecca to Yathrib (now Medina) in 622 CE. This event, known as the Hijrah, is commemorated in Islam for its role in the founding of the first Muslim community (''ummah''). Currently, the Hijri year is . In the West, this era is most commonly denoted as AH (, , ) in parallel with the Christian/Common (AD/CE) and Jewish eras (AM) and can similarly be placed before (preferably) or after the date. In predominantly Muslim countries, it is also commonly abbreviated H ("Hijra") from its Arabic abbreviation (). Years prior to AH 1 are reckoned in English as BH ("Before the Hijra"), which should follow the date. A year in the Islamic lunar calendar consists of twelve lunar months and has only 354 or 355 days in its year. Consequently, its New Year's Day occurs ten days earlier each year relative to the Gregorian ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Ibn Saud
Abdulaziz bin Abdul Rahman Al Saud (; 15 January 1875Ibn Saud's birth year has been a source of debate. It is generally accepted as 1876, although a few sources give it as 1880. According to British author Robert Lacey's book ''The Kingdom'', a leading Saudi historian found records that show Ibn Saud in 1891 greeting an important tribal delegation. The historian reasoned that a 10 or 11-year-old child (as given by the 1880 birth date) would have been too young to be allowed to greet such a delegation, while an adolescent of 15 or 16 (as given by the 1876 date) would likely have been allowed. When Lacey interviewed one of Ibn Saud's sons prior to writing the book, the son recalled that his father often laughed at records showing his birth date to be 1880. Ibn Saud's response to such records was reportedly that "I swallowed four years of my life." p. 561" – 9 November 1953), known in the Western world as Ibn Saud (; ''Ibn Suʿūd''),''Ibn Saud'', meaning "son of Saud" (see Arabi ...
