What is a Coin?

A coin is a piece of metal (rarely some other material, such as leather or porcelain) certified by a mark or marks upon it as being of a specific intrinsic or exchange value. It was a medium of exchange in early money systems and is one of the oldest forms of money. Early coins were crude, but by the 4th century bc, Greek and then Roman coinage had evolved into works of remarkable artistic beauty. Coins provide a remarkable window on the artistic achievements of their time, as well as on the social and political structures that produced them.

Historically, coins were made of precious metals such as gold and silver. Later, copper and other metals were used. Today, most coins are made of a mix of alloys such as cupro-nickel (copper 75%, nickel 5% and zinc 20%, with a little silver in color), brass (copper, zinc, manganese and sometimes nickel) or simple plated steel. Occasionally, two metals are combined to create a bimetallic coin, such as the euro and the British pound.

Some coins contain a date or other information in an area called the exergue. Other coins, particularly older ones, have no exergue at all. The exergue may contain a privy mark or a legend, depending on the coin’s design. Most coins have a raised edge called the rim, but some have flat edges.

In addition to their monetary value, coins have significant historical significance and are often collectors’ prized possessions. Some people collect only modern commemorative coins, while others focus on collecting the coins of their country or region. The earliest coins were made of electrum, a naturally occurring alloy of gold and silver. As societies developed, the use of gold and silver declined, but coins continued to be produced in many countries.
