Introducing Currency

Currency is the most important form of money in the present world. But it was not always like this. Earlier, coins usually made of gold or silver was used as a form of money. Coins have a natural or inherent value. Gold coins were used for large purchases while silver or copper coins were used for smaller purchases during the medieval period. However, this has been replaced with banknotes. Banknotes are worthless otherwise in terms of natural or inherent value unlike gold coins. These banknotes get the value by decree of the government who declare the banknotes as money.
