South Korean Won
The Korean Republic won, unofficially the South Korean won ( Symbol: ₩; Code: KRW; Korean: 대한민국 원) is the official currency of South Korea. A single won is divided into 100 jeon, the monetary subunit. The jeon is no longer used for everyday transactions, and it appears only in foreign exchange rates. The currency is issued by the Bank of Korea, based in the capital city of Seoul. Etymology The old "won" was a cognate of the Chinese yuan and Japanese yen, which were both derived from the Spanish-American silver dollar. It is derived from the hanja (, ''won''), meaning "round", which describes the shape of the silver dollar. The won was subdivided into 100 ''jeon'' (), itself a cognate of the Chinese unit of weight mace and synonymous with money in general. The current won (1962 to present) is written in hangul only and does not officially have any hanja associated with it. First South Korean won History The Korean won, Chinese yuan and Japanese yen were ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Cupronickel
Cupronickel or copper-nickel (CuNi) is an alloy of copper that contains nickel and strengthening elements, 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, petrochemical, and electrical industries. Another common 20th-century use of cupronickel was silver-coloured coins. For this use, the typical alloy has 3:1 copper to nickel ratio, with very small amounts of manganese. In the past, true silver coins were debased with cupronickel, such as coins of the pound sterling from 1947 onwar ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Copper
Copper is a chemical element with the symbol Cu (from la, cuprum) and atomic number 29. It is a soft, malleable, and ductile metal with very high thermal and electrical conductivity. A freshly exposed surface of pure copper has a pinkish-orange color. Copper is used as a conductor of heat and electricity, as a building material, and as a constituent of various metal alloys, such as sterling silver used in jewelry, cupronickel used to make marine hardware and coins, and constantan used in strain gauges and thermocouples for temperature measurement. Copper is one of the few metals that can occur in nature in a directly usable metallic form ( native metals). This led to very early human use in several regions, from circa 8000 BC. Thousands of years later, it was the first metal to be smelted from sulfide ores, circa 5000 BC; the first metal to be cast into a shape in a mold, c. 4000 BC; and the first metal to be purposely alloyed with another metal, tin, to create ...

Nickel
Nickel is a chemical element with 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 classified as an e ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Red-crowned Crane
The red-crowned crane (''Grus japonensis''), also called the Manchurian crane or Japanese crane (; the Chinese character '丹' means 'red', '頂/顶' means 'crown' and '鶴/鹤' means 'crane'), is a large East Asian crane among the rarest cranes in the world. In some parts of its range, it is known as a symbol of luck, longevity, and fidelity. Description Adult red-crowned cranes are named for a patch of red bare skin on the crown, which becomes brighter during the mating season. Overall, they are snow white in color with black on the wing secondaries, which can appear almost like a black tail when the birds are standing, but the real tail feathers are actually white. Males are black on the cheeks, throat, and neck, while females are pearly gray in these spots. The bill is olive green to a greenish horn, the legs are slate to grayish black, and the iris is dark brown.Archibald G.W. & Meine, C.D. 1996. ''Family Gruidae (Cranes)''.

Bank Of Korea
The Bank of Korea (BOK; ) is the central bank of the Republic of Korea and issuer of Korean Republic won. It was established on 12 June 1950 in Seoul, South Korea. The bank's primary purpose is price stability. For that, the bank targets inflation. The 2016–18 target is consumer price inflation of 2.0%. History 1945-1970 The Bank of Korea was established on June 12, 1950 under the Bank of Korea Act. Following liberation on August 15, 1945, the Korean economy was plunged into turmoil. Tackling the severe inflation and financial disorder brought about by an acute shortage of resources and the division of the country along the 38th parallel was the immediate priority. In this situation, discussions raged across the country on establishing a central bank for the Republic of Korea and Dr. A.I. Bloomfield, dispatched from the Federal Reserve Bank of New York, drafted the Bank of Korea Act. Based on this draft, the Bank of Korea Act was passed in May 1950 and the bank launched it ...

500 Yen Coin
The is the largest denomination of Japanese yen coin issued for circulation. These coins were first struck in 1982 as the vending machine industry needed a higher valued coin for use in their machines. The denomination had previously been issued as paper currency which co-circulated with the new coins until 1994. Originally the 500 yen coin was made up of cupronickel, but was later changed to nickel brass, and then to bi-metallic to deter counterfeiting. This illegal practice has been a constant issue since the coin was first released due to its high purchase value. With a history spanning 3 imperial eras, 500 yen coins are also collectibles. History Cupronickel yen The 500 yen coin was first minted in 1982 as another coin denomination was needed for use in vending machines. The obverse of the cupronickel based 500 yen coin features a paulownia crest, while the reverse is designed with bamboo and Tachibana. These elements were chosen as they are regarded as symbols of goo ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
