Why we stopped using coins??
Where did the coins went?? What if we start to use again? Did RMA collect it back???
The coins have value to earn something in economic way. If we start to reuse and it is reusable. The developed countries across have a habit to use coins and the highest denomination of USA is $100 whereby we are under-developing country and we don't have a habit of valuing a coins and even nu. 1/-.
The inflation takes places yearly,the real gdp is decreasing with increasing of nominal gdp. The money supply increases yearly. What if we start to use coins, the printing expenses of currency may reduce somehow. Reusing may be helpful in some other way....
The value of Nu. 1 is not equal to any chocolates you get back!
