Children: So we should check each and every note that we receive?
Money Kumar: Ideally you should check & count all your money. I know it's difficult. But you can be careful. After all, it's your money, isn't it?

Children: Money Kumar, what about the coins in my piggy bank? Will the bank give me some nice notes in exchange?

Money Kumar: Sure! Give me your piggy bank.

The piggy bank is overflowing with coins of five and ten paise coins. Money Kumar and the lady exchange a quick glance at each other and smile. The lady quickly counts the coins and gives the children notes of their equivalent value. The ice-cream vendor also quietly empties his box of 25 and 50 paise coins and takes fresh notes from the lady.

Children: Why don't people accept such coins these days?
Money Kumar: Let me explain. Do you know how much your t-shirt costs?
