The East Caribbean dollar (XCD) is a type of money used in many countries in the Caribbean, like Antigua and Barbuda, Dominica, Grenada, Saint Kitts and Nevis, and Saint Lucia. You can use it to buy things in these countries, just like you would with coins and dollars in the United States. It is a very useful currency, because it is easy to use and helps people in the Caribbean buy the things they need.
