Coins are small, round pieces of metal that people use as money. They come in different sizes, shapes, and values, often featuring images of important figures or symbols from a country. Coins are made from various metals, such as copper, nickel, and silver, and are used for everyday transactions, like buying snacks or paying for bus fare. In addition to their practical use, coins can also be collected as a hobby. Many people enjoy gathering rare or historical coins, which can be valuable over time. Collecting coins can teach us about history and culture, making it a fun and educational activity for all ages.
