Gold Coin
A gold coin is a coin that is made mostly or entirely of gold. Most gold coins minted since 1800 are 90–92% gold (22karat), while most of today's gold bullion coins are pure gold, such as the Britannia, Canadian Maple Leaf, and American Buffalo. Alloyed gold coins, like the American Gold Eagle and South African Krugerrand, are typically 91.7% gold by weight, with the remainder being silver and copper. Traditionally (up to about the 1930s), gold coins have been circulation coins, including coin-like bracteates and dinars. In recent decades, however, gold coins are mainly produced as bullion coins for investors and as commemorative coins for collectors. While modern gold coins are still legal tender, they are not observed in everyday financial transactions, as the metal value normally exceeds the nominal value. For example, the American Gold Eagle has a denomination of 10 USD, but a metal value of more than $800 USD (being around a half an ounce). The gold reserves of cent ...

Financial Transaction
A financial transaction is an Contract, agreement, or communication, between a buyer and seller to exchange goods, Service (economics), services, or Asset, assets for payment. Any transaction involves a change in the status of the finances of two or more businesses or individuals. A financial transaction always involves one or more financial asset, most commonly money or another valuable item such as gold or silver. There are many types of financial transactions. The most common type, purchases, occur when a good, service, or other commodity is sold to a consumer in exchange for money. Most purchases are made with cash payments, including Cash, physical currency, Debit card, debit cards, or Cheque, cheques. The other main form of payment is credit, which gives immediate access to funds in exchange for repayment at a later date. History There is no evidence to support the theory that ancient civilizations worked on systems of barter. Instead, most historians believe that ancient ...

Gold Solidus Of Valentinian II - Obverse YORYM 1998 853
Gold is a chemical element with the symbol Au (from la, aurum) and atomic number 79. This makes it one of the higher atomic number elements that occur naturally. It is a bright, slightly orange-yellow, dense, soft, malleable, and ductile metal in a pure form. Chemically, gold is a transition metal and a group 11 element. It is one of the least reactive chemical elements and is solid under standard conditions. Gold often occurs in free elemental ( 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 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). Gold is resistant to most acids, though it does dissolve in aqua regia (a mixture of nitric acid and hydrochloric acid), forming a soluble tetrachloroaurate anion. Gol ...

Achaemenid Coin Daric 420BC Front
The Achaemenid Empire or Achaemenian Empire (; peo, 𐎧𐏁𐏂, , ), also called the First Persian Empire, was an ancient Iranian empire founded by Cyrus the Great in 550 BC. Based in Western Asia, it was contemporarily the largest empire in history, spanning a total of from the Balkans and Egypt in the west to Central Asia and the Indus Valley in the east. Around the 7th century BC, the region of Persis in the southwestern portion of the Iranian plateau was settled by the Persians. From Persis, Cyrus rose and defeated the Median Empire as well as Lydia and the Neo-Babylonian Empire, marking the formal establishment of a new imperial polity under the Achaemenid dynasty. In the modern era, the Achaemenid Empire has been recognized for its imposition of a successful model of centralized, bureaucratic administration; its multicultural policy; building complex infrastructure, such as road systems and an organized postal system; the use of official languages across its t ...

Counterfeit
To counterfeit means to imitate something authentic, with the intent to steal, destroy, or replace the original, for use in illegal transactions, or otherwise to deceive individuals into believing that the fake is of equal or greater value than the real thing. Counterfeit products are fakes or unauthorized replicas of the real product. Counterfeit products are often produced with the intent to take advantage of the superior value of the imitated product. The word ''counterfeit'' frequently describes both the forgeries of currency and documents as well as the imitations of items such as clothing, handbags, shoes, pharmaceuticals, automobile parts, unapproved aircraft parts (which have caused many accidents), watches, electronics and electronic parts, software, works of art, toys, and movies. Counterfeit products tend to have fake company logos and brands, which results in patent or trademark infringement in the case of goods. They also have a reputation for being lower qual ...

Density
Density (volumetric mass density or specific mass) is the substance's mass per unit of volume. The symbol most often used for density is ''ρ'' (the lower case Greek letter rho), although the Latin letter ''D'' can also be used. Mathematically, density is defined as mass divided by volume: : \rho = \frac where ''ρ'' is the density, ''m'' is the mass, and ''V'' is the volume. In some cases (for instance, in the United States oil and gas industry), density is loosely defined as its weight per unit volume, although this is scientifically inaccurate – this quantity is more specifically called specific weight. For a pure substance the density has the same numerical value as its mass concentration. Different materials usually have different densities, and density may be relevant to buoyancy, purity and packaging. Osmium and iridium are the densest known elements at standard conditions for temperature and pressure. To simplify comparisons of density across different s ...

Commodities
In economics, a commodity is an economic good, usually a resource, that has full or substantial fungibility: that is, the market treats instances of the good as equivalent or nearly so with no regard to who produced them. The price of a commodity good is typically determined as a function of its market as a whole: well-established physical commodities have actively traded spot and derivative markets. The wide availability of commodities typically leads to smaller profit margins and diminishes the importance of factors (such as brand name) other than price. Most commodities are raw materials, basic resources, agricultural, or mining products, such as iron ore, sugar, or grains like rice and wheat. Commodities can also be mass-produced unspecialized products such as chemicals and computer memory. Popular commodities include crude oil, corn, and gold. Other definitions of commodity include something useful or valued and an alternative term for an economic good or servic ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Fungible
In economics, fungibility is the property of a good or a commodity whose individual units are essentially interchangeable, and each of whose parts is indistinguishable from any other part. Fungible tokens can be exchanged or replaced; for example, a $100 note can easily be exchanged for twenty $5 bills. In contrast, non-fungible tokens cannot be exchanged in the same manner. For example, gold is fungible because its value doesn’t depend on any specific form, whether of coins, ingots, or other states. However, a unique item such as a gold statue by a famous artist would not be considered fungible. In short, a thing is fungible when all equivalent amounts of that thing are interchangeable. Fungible commodities include sweet crude oil, company shares, bonds, other precious metal Precious metals are rare, naturally occurring metallic chemical elements of high economic value. Chemically, the precious metals tend to be less reactive than most elements (see noble meta ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Gold Bar
A gold bar, also called gold bullion or gold ingot, is a quantity of refined metallic gold of any shape that is made by a bar producer meeting standard conditions of manufacture, labeling, and record keeping. Larger gold bars that are produced by pouring the molten metal into molds are called ingots. Smaller bars may be manufactured by minting or stamping from appropriately rolled gold sheets. The standard gold bar held as gold reserves by central banks and traded among bullion dealers is the Good Delivery gold bar. The kilobar, which is in mass, and a 100 troy ounce gold bar are the bars that are more manageable and are used extensively for trading and investment. The premium on these bars when traded is very low over the spot value of the gold, making it ideal for small transfers between banks and traders. Most kilobars are flat, although some investors, particularly in Europe, prefer the brick shape. Types Based upon how they are manufactured, gold bars are categorized a ...

Central Bank
A central bank, reserve bank, or monetary authority is an institution that manages the currency and monetary policy of a country or monetary union, and oversees their commercial banking system. In contrast to a commercial bank, a central bank possesses a monopoly on increasing the monetary base. Most central banks also have supervisory and regulatory powers to ensure the stability of member institutions, to prevent bank runs, and to discourage reckless or fraudulent behavior by member banks. Central banks in most developed nations are institutionally independent from political interference. Still, limited control by the executive and legislative bodies exists. Activities of central banks Functions of a central bank usually include: * Monetary policy: by setting the official interest rate and controlling the money supply; *Financial stability: acting as a government's banker and as the bankers' bank ("lender of last resort"); * Reserve management: managing a country ...

Gold Reserve
A gold reserve is the gold held by a national central bank, intended mainly as a guarantee to redeem promises to pay depositors, note holders (e.g. paper money), or trading peers, during the eras of the gold standard, and also as a store of value, or to support the value of the national currency. The World Gold Council estimates that all the gold ever mined, and that is accounted for, totalled 190,040 metric tons in 2019How much gold has been mined? , World Gold Council but other independent estimates vary by as much as 20%. At a price of US, reached on 16 August 2017, one metric ton of gold has a value of approximately $40.2 million. The total value of all gold ever mined, and that is accounted for, would exceed $7.5 trillion at that valuation and using WGC 2017 estimates.
