Coin
(Redirected from Exergue)
Coin is a small, flat, (usually, depending on the country or value) round piece of metal or plastic used primarily as a medium of exchange or legal tender. They are standardized in weight, and produced in large quantities at a mint in order to facilitate trade. They are most often issued by a government. Coins are usually metal or an alloy, or sometimes made of synthetic materials. They are usually disc shaped. Coins made of valuable metal are stored in large quantities as bullion coins. Other coins are used as money in everyday transactions, circulating alongside banknotes. Usually the highest value coin in circulation (excluding bullion coins) is worth less than the lowest-value note. In the last hundred years, the face value of circulation coins has occasionally been lower than the value of the metal they contain, for example due to inflation.
History[edit | edit source]
Coins are historical artifacts that reflect the political, socio-economic, and cultural aspects of the time in which they were made. The study of coins and their history is known as numismatics. The first coins were created in Iron Age Anatolia (modern-day Turkey) in the 7th century BC by the Lydians. These early coins were made of electrum, a naturally occurring alloy of gold and silver, and were stamped with pictures that acted as denominations. In the years that followed, coined money was adopted by the Persian Empire and spread across the Greco-Roman world, facilitating trade and commerce.
Manufacturing[edit | edit source]
The process of coin manufacturing is known as minting. Coins are produced in various mints around the world. The design of a coin is typically approved by a national authority, such as a mint or the treasury. The manufacturing process includes the creation of a die that stamps the coins with their designs. Modern coins are manufactured through a high-speed coining process, where blanks are inserted into presses that stamp them at a rate of thousands per hour.
Design[edit | edit source]
The design of coins has evolved significantly over time. Early coins were simple in design, with one side featuring an emblem or symbol and the other side featuring a punch mark. As technology advanced, the designs became more complex and artistic, often featuring portraits of significant individuals, such as monarchs or national heroes, emblems, and symbols of national identity. The edge of a coin can also be designed, with inscriptions, grooves, or reeding.
Collecting[edit | edit source]
Coin collecting is a popular hobby known as numismatics. Collectors may value a coin based on its historical significance, rarity, condition, and beauty. Some coins are collected for their historical association, others for the challenge of completing a collection, and some for a potential increase in value.
Circulation and Value[edit | edit source]
The value of a coin is determined by its nominal value as well as its material value. Circulation coins are those used in daily transactions and their value is primarily symbolic, as their material value is often less than their face value. Commemorative coins, on the other hand, are often made of precious metals and their value can exceed their face value.
Digital and Cryptocurrency[edit | edit source]
In the 21st century, the concept of coins has expanded beyond physical objects to include digital formats, such as cryptocurrency. Cryptocurrencies are digital or virtual currencies that use cryptography for security and operate independently of a central bank. The most well-known cryptocurrency is Bitcoin, which was introduced in 2009.
Conclusion[edit | edit source]
Coins are a fundamental aspect of human history and economy, serving as a medium for trade, a reflection of society, and a collector's item. Their design, manufacturing, and value reflect the technological, political, and cultural changes of societies throughout history.
