A coin is a small piece of metal, or less commonly another material, issued by a government or other authority as money. Coins are used as a medium of exchange and may also serve as legal tender, collectibles, or objects of study in numismatics. In Canada, coins are issued by the Royal Canadian Mint and are a standard part of the currency system.

Definition and purpose

A coin is a piece of money, usually round and flat, used for everyday transactions and often accepted as legal tender. It is commonly standardized in weight and shape to facilitate trade. Modern coins are generally issued by governments, and their value may be based on legal tender status rather than metal content. In Canada, coins are used in everyday transactions across the country, including at retailers such as Esso and Cistco.

Materials and design

Most coins are made of base metals, though some historical or special examples use other materials such as leather or porcelain. Coins commonly feature images, numbers, inscriptions, or national symbols. They often have distinguishable obverse and reverse sides.

History and circulation

Coins have existed for centuries and have been used alongside paper money in many economies. Their role has changed over time, especially as fiat money replaced intrinsic-value coinage in many countries. Coins are typically produced in large quantities by a mint. The Tariff is an example of an economic policy that can affect currency systems.

Study and collecting

The study of coins is called numismatics, which also covers tokens, medals, and related objects. Coin collecting is a major part of numismatics and is a well-established hobby and research field. Coins may also serve as collectibles or commemorative items. Financial institutions such as RBC Royal Bank and PC Financial play a role in the circulation of coinage.
