Children: But if no one takes these coins, why would a bank accept them? What will it do with these coins?
Money Kumar: You're right. So, the best thing to do is to go and deposit these unusable coins in a bank.

Money Kumar: Banks will accept them because that's their job. And if no one accepts them, they will send those coins back to the Reserve Bank. The Reserve Bank will send them to the mint for melting them. The same is the fate of currency notes. When they become too dirty and unusable, the Reserve Bank destroys them by shredding them into tiny pieces and turning them into briquets.

The kids are horrified

Children: You mean, those coins and notes will vanish? We won't see them any more?
