Money is used for buying things. The history of money is very interesting. Thousands of years ago, instead of using money, people used the barter system, exchange of things, to get the things they needed. Later, grains, cows, salt, etc., were accepted as money. Eventually, gold and silver took the place of grain, cattle, salt, etc. And slowly, an organised money system called the currency system came into play. Today, the ruling authority of a region issues coins and paper money accepted by all. These coins and paper money hold a specific value with which a person can buy things and can save money for future payments as well.
