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

Money Kumar: Perhaps not, unless you visit the RBI's Monetary Museum!
Children: Wow! When we will you take us there?

Money Kumar: Oh, it's right on your computer. Check it out at www.museum.rbi.org.in. But we will certainly visit it some day!
