Q.Describe the main stages in the evolution of money.

Money took its present forms only gradually, as exchange itself grew wider and more complex over history.

Money evolved through several broad, overlapping stages:

1. Barter — the earliest stage, in which goods were exchanged directly for other goods, with no medium of exchange at all.
2. Commodity money — a widely wanted, reasonably durable and divisible commodity (cattle, grain, salt, cowrie shells) was accepted as a common medium of exchange, since it carried value of its own.
3. Metallic money — as trade widened, communities shifted to metals (gold, silver, copper), whose value could be judged by weight and purity, and later to standard coins struck by a recognised authority.
4. Paper money — as trade volumes grew beyond what could conveniently be carried in metal, currency notes were issued, valued on the strength of legal backing and public confidence rather than the paper itself.
5. Credit (bank) money — funds held as bank deposits and transferred by cheque, demand draft, or electronic transfer, without physical currency changing hands.
6. Plastic and digital money — debit/credit cards and mobile-linked systems (UPI, digital wallets), allowing near-instant transfer of a bank deposit without cash or even a physical card.

It is important to note that these stages overlap rather than replace each other in strict sequence — cash, bank deposits, and digital payments all circulate together in India today — but the broad historical direction has been from a bulky, physical, perishable commodity towards an increasingly abstract, trusted record of value.

Presenting the stages as if each one completely vanished once the next appeared — in reality metallic coins, paper currency, bank money, and digital money all still circulate side by side.
