Currency is the type of money that a country uses. It can be paper bills or coins that you can use to buy goods and services. You may use currency to buy things at a store or online, or when you travel to a different country. Each country has their own currency, such as US dollars, euros, British pounds, or Japanese yen. When talking about currency, we also talk about exchange rates, which is the value of one country's currency compared to another country's currency.
