Local currencies are different kinds of money that are used in specific areas like cities or towns. They are usually different from the official money that is used for most transactions, like the U.S. Dollar. These local currencies can help keep money from leaving the area, which helps support local businesses and the local economy. For example, if you own a restaurant in a town, you might accept the local currency instead of U.S. Dollars. This means that people in the town will keep their money in the local area instead of going somewhere else.
