What Is a Coin?

A coin is a piece of metal that functions as currency. It can be used to buy goods or services, and it can also be stored for future use. There are many different types of coins, from the penny to the dollar. Coins are typically made of precious metals such as gold, silver, or bronze. They may be dated to show the year that they were minted. Many people collect coins, either for their intrinsic value or for historical significance. The inscriptions and illustrations on ancient coins often provide unique insight into the culture of the time when they were created.

The term coin can also be used to refer to a cryptocurrency that operates independently of other coins and acts as the native currency within a blockchain network. These coins are sometimes called tokens, but they differ from tokens in that they are not designed to serve utility functions such as providing voting rights or denoting cloud storage capacity.

The word coin was first used in the Middle English period (1150–1500), and has 16 meanings listed in the Oxford English Dictionary (OED). The earliest evidence of the verb to coin is found in 1330, and is closely related to money. Coins are often rubbed and polished, but this can decrease their value by removing bits of metal or leaving oils from the hands. A good rule is to always hold a coin by the edges with one hand and never touch its surface.

Minting began in the 6th century bc in Lydia, and the art soon spread to other parts of the world. The ancient Greeks minted gold and silver coins, but later they added copper to their currency as a cheaper material. This practice, known as debasement, allowed a government to produce more coins than it would have otherwise been possible with pure metals alone. It has been used to make coins lighter and less likely to wear down, but it also increases their cost.

Modern mints usually produce coins of a single metal, although bimetallic coins are also common. They may have a space on their exergue for a date, privy mark, or other design element, but most have no such feature. The relationship between the images on a coin’s obverse and reverse is called its medallic orientation. If turning a coin left or right on its vertical axis reveals that the reverse image is the same as the obverse, it has correct orientation.

The coins of a particular country are often distinguished by their designs, and this is especially true of rare or commemorative specimens. Collectors of coins tend to specialize in collecting a certain type, and they will seek to complete their set by obtaining examples from each year of issue. For some types of coins, a particular rarity can be worth a significant sum of money. A coin collection is often displayed in a case or box, and a careful record is kept of each piece.
