However since coins have a critical role in pricing of our goods and services and facilitate economic growth through trading coins must be made available to the economy. Let me remind you that the basic unit of our currency is the one dollar. One dollar is made up of 100 cents and prices can fall as fraction of the one dollar.
For example if we have no smaller coins, the prices of goods or services will start from one dollar and will increase by the multiples of one dollar. To void this possibility of unfair pricing, coins are issued at different face value to help with pricing of goods and services.
