The Big Questions
This chapter centres on three fundamental questions that are crucial for understanding economic history:
- How did exchange take place before money?
- Why did money come into existence?
- How has money transformed into various forms over time?
In earlier themes, we read about crops people grew (like food grains) or goods they made (like carnelian beads). The question arises — how did they exchange these goods for things they needed? The answer lies in the barter system and its eventual evolution into money.
The Barter System
People exchanged goods or services for other goods and services without using money. This system is called the barter system. It was the earliest form of exchange and there is a lot of evidence of it from around the world.
Suppose you need a pencil and have an extra eraser. Your classmate forgot to bring their eraser but has an extra pencil. You exchange your eraser for your classmate’s pencil — both needs are satisfied. This is how the barter system works.
People used various commodities as mediums of exchange under the barter system:
- Cowrie shells
- Salt
- Tea
- Tobacco
- Cloth
- Cattle — cows, goats, horses, sheep
- Seeds
| Term | Definition |
|---|---|
| Barter System | A way of exchanging goods and services without using money |
| Transaction | A piece of business done between people — especially an act of buying or selling |
| Commodities | Products or goods that can be traded, bought, and sold |
| Money | The common tool that everybody accepts and uses in order to make or receive payments in exchange for goods and services |
Unusual Forms of Money Around the World
Across the globe, different civilisations used very different objects as money. These examples illustrate how the concept of a “medium of exchange” is universal, even if its form varies dramatically.
| Object | Region | Description |
|---|---|---|
| Rai Stones | Yap Island, Micronesia (Pacific Ocean) | Giant discs of rock used as money. Their large size meant ownership changed hands without physically moving them. |
| Aztec Copper Tajadero | Central Mexico & parts of Central America | Copper chopping-knife-shaped objects used as currency. “Tajadero” is a Spanish word for “chopping knife.” |
| Tevau | Solomon Islands | Red feather coils made from birds’ feathers, used as a medium of exchange. |
| Cowrie Shells | Pan-Asian, African, Indian subcontinent | Small shells widely used as a common currency across many civilisations for thousands of years. |
Why Do We Need Money? — Limitations of Barter
The barter system, while functional in small communities, had serious structural problems that made trade increasingly difficult as economies grew. NCERT presents this beautifully through the story of a farmer with an ox.
Imagine you are a farmer. You need shoes, a sweater, and medicines for your grandmother. You only have an ox to spare. Problems you would face:
Step 1: Find someone who needs an ox AND has shoes, a sweater, and medicines — nearly impossible.
Step 2: You may exchange the ox for several bags of wheat — but is that a fair exchange for shoes?
Step 3: You’d carry bags of wheat to multiple locations to find a shoe-seller, sweater-seller, and medicine-seller separately.
Step 4: Leftover wheat must be stored safely — but it rots or gets eaten by rats.
The Five Core Problems of Barter
| Problem | Definition | Example |
|---|---|---|
| Double Coincidence of Wants | Both parties must want exactly what the other has to offer — simultaneously | The farmer needs someone who wants an ox AND has a sweater to give |
| No Common Standard Measure of Value | No agreed-upon worth for comparing different goods | How many bags of wheat equal one pair of shoes? No common unit to compare |
| Divisibility Problem | Goods cannot always be split into smaller parts for partial exchange | You cannot cut the ox in half to exchange for just a sweater |
| Portability Problem | Many goods are too heavy or bulky to carry around for trade | Carrying an ox — or bags of wheat — everywhere is impractical |
| Durability Problem | Many goods used in barter perish quickly and cannot be stored for future use | Wheat rots or gets eaten by rats — you cannot save it as “wealth” for later |
Double coincidence of wants is a foundational economic concept. It describes a situation where two people each have something the other wants AND can exchange them directly. This condition was extremely difficult to satisfy in daily barter-based economies, making the system inherently inefficient.
The solution to all these problems was a common medium of exchange — money.
Basic Functions of Money
As trade expanded in volume and geography, a common medium of exchange became essential. Money came into existence and became the accepted method of payment. Money solves all the core problems of barter:
| Function of Money | How it Solves Barter’s Problem | Example |
|---|---|---|
| Medium of Exchange | Eliminates the need for double coincidence of wants | Farmer sells ox for money; uses money to buy shoes, sweater, and medicines separately |
| Store of Value | Solves the durability problem — money doesn’t rot | Farmer can keep money for months and use it later, unlike wheat which would rot |
| Common Denomination / Measure of Value | Solves the lack of common standard measure of value | Price of shoes = ₹500, sweater = ₹800. Easily comparable in a common unit |
| Standard of Deferred Payment | Allows payments to be made in the future (credit) | You have ₹50 but need a ₹100 book — shopkeeper can allow you to pay ₹50 later |
| Portability | Money is compact and easy to carry | A ₹2000 note is infinitely easier to carry than bags of wheat |
| Divisibility | Money can be divided into any denomination | ₹100 can be broken into ₹50 + ₹20 + ₹20 + ₹10 — no such option with an ox |
Parents pay money to shopkeepers → Shopkeepers pay salaries to workers → Workers buy everyday essentials, pay school fees, etc. → The same money circulates through the economy, serving everyone’s needs. This illustrates how money acts as a universal medium that links all economic activities.
Key Facts About Functions of Money
- Money as a store of value means it can be kept and used in future transactions — unlike perishable commodities.
- Money as a standard of deferred payment means you can borrow now and pay later — the foundation of credit.
- Money as a common denomination allows the price of any good or service to be expressed in one unit — enabling comparisons.
- Keynes said money is a link between the present and the future — you earn today and spend tomorrow.
The Journey of Money — A Timeline
The evolution of money in India follows a broad timeline spanning thousands of years, from simple barter to digital transactions:
| Period / Year | Form of Money | Key Features |
|---|---|---|
| ~6000 BCE | Barter System | Direct exchange of goods and services; no money involved |
| ~1000 BCE onwards | Cowrie Shells | Widely used as commodity money across India and other civilisations; continued in use for a very long time |
| ~600 BCE | Metal Coinage (Iron, Silver, Gold, Copper) | Punch-marked coins; called kārṣhāpaṇas or paṇas; symbols called rūpas punched on them |
| 1861 | Official Paper Money | Paper Currency Act 1861; centralised currency issue in India under British rule |
| ~1980 | Debit & Credit Cards | Digital money backed by bank accounts; physical cards for non-cash transactions |
| 2016 | UPI (Unified Payments Interface) | Instant digital payment via mobile; QR code based; no physical card needed |
Coinage in India — Ancient to Modern
Coins were among the earliest forms of money. Rulers issued coins used by their citizens for transactions. Each kingdom had its own coinage, and the minting and issuance of coins was controlled entirely by rulers. Over time, coins of powerful rulers were accepted across various kingdoms, facilitating trade across geographies.
Ancient Indian Coins
- Made from precious metals: gold, silver, copper or their alloys
- Called kārṣhāpaṇas or paṇas
- Had symbols punched on them called rūpas
- The two sides of a coin: obverse (head/principal design) and reverse (tail)
- Motifs included: animals, trees, hills, kings/queens, deities
- The word ‘paṇa’ continues in modern Indian languages: Tamil/Telugu/Malayalam — paṇam; Kannada — haṇa. These are derivatives used for “money.”
- Alloys of silver and copper were used for ancient coins. Modern Indian coins are alloys largely of iron with chromium, silicon, and carbon in precise proportions.
- The Chalukyas of Kalyana had a Varaha image (avatar of Viṣhṇu) on one side and a decorated three-tiered Royal Parasol on the other.
- The Cholas (850–1279 CE) used a silver coin with a tiger emblem — their royal symbol.
Roman Gold Coins in India — Trade Evidence
Roman gold coins were found during excavations in Pudukottai, Tamil Nadu. Their heads embossed are those of Roman kings. What can we conclude?
The discovery of Roman coins in Tamil Nadu proves that southern India had active maritime trade with Rome. Scholars conclude that the trade was in India’s favour — Rome was paying India (in gold coins) for Indian goods like spices, textiles, and gems. This is supported by Roman historian Pliny who complained about gold draining from Rome to India.
Anna System — Pre-Independence Currency
1 anna = 1/16 of a rupee. In 1947, one anna could buy a dozen bananas. The anna system shows the earlier decimal and sub-decimal structure of Indian currency before full decimalisation in 1957.
After independence, special coins are minted to mark important national events — e.g., a ₹20 coin to mark India’s 75 years of Independence in 2021.
The Indian Rupee Symbol (₹)
The ₹ sign was adopted by the Government of India in 2010. It was designed by Udaya Kumar from the Indian Institute of Technology (IIT), Bombay (Mumbai).
The symbol is a blend of the Devanagari “Ra” (र) and the Roman “R” with two parallel horizontal stripes running at the top — representing the national flag and also the “equal to” (=) sign, symbolising equality.
Minting — Key Concept
Minting is the process of producing coins. A mint refers to a manufacturing facility that produces coins used as a nation’s currency. In ancient times, rulers controlled minting. Today in India, the Reserve Bank of India (RBI) oversees currency, and coins are minted at government mints.
Today, Indian coins feature both Hindi and English text and are made in various denominations. Special commemorative coins are also issued.
Paper Money & Currency
As coins became used for all types of exchanges — from buying vegetables to purchasing land — it became difficult to carry and store large quantities of coins. The search for an alternative ended with paper money.
| Aspect | Detail |
|---|---|
| First Use of Paper Money | China — paper money was first used in the world |
| Introduction in India | Late 18th century (under British rule) |
| First Banks to Issue Notes | Bank of Bengal (uniface notes), Bank of Bombay (₹10 notes) |
| Paper Currency Act | 1861 — Official paper money centralised in India |
| Current Authority | Reserve Bank of India (RBI) — the only legal authority to issue currency in India |
Today, the Reserve Bank of India (RBI) is the central authority that controls the issue of currency. It is not legal for anybody other than the RBI to issue currency. To prevent illegal printing, the RBI has introduced many security features on notes.
Denominations of Indian Currency:
- Coins: 50 paisa, ₹1, ₹2, ₹5, ₹10, ₹20
- Paper notes: ₹10, ₹20, ₹50, ₹100, ₹200, ₹500 (and previously ₹1000)
While coins are used for smaller denominations, paper currency is used for higher denominations.
Arthaśhāstra on Paṇas — Key UPSC Fact
- The Arthaśhāstra states: “An annual salary of 60 paṇas could be substituted by an āḍhaka of grain per day, enough for four meals.”
- One āḍhaka = approximately 3 kg of grain.
- The fine for failing to help a neighbour was 100 paṇas — higher than the annual salary of 60 paṇas. This indicates the high value placed on social responsibility and community values in ancient India.
New Forms of Money — Digital Payments
As technology advanced, money took intangible forms — forms we cannot touch and feel. This is called digital money, which exists in electronic form.
| Payment Method | Description |
|---|---|
| Debit Cards | Directly linked to your bank account; money is deducted immediately on transaction |
| Credit Cards | Borrow money from the bank; repay later with possible interest |
| Net Banking | Transfer funds via the internet using bank portals |
| UPI — Unified Payments Interface | Instant real-time payment via mobile app; introduced 2016; India’s most widely used digital payment system |
| QR Code Payments | Customers scan a Quick-Response code with their phone; payment goes directly into the seller’s bank account |
QR Code stands for Quick-Response Code. These are collections of black and white squares, readable by devices like smartphones and QR scanners. They contain information about the receiver’s bank account and are used for making monetary transactions. Even small street vendors like fruit sellers now use QR code payments.
Example: Krishnappa, a seasonal fruit seller, displays a card with a QR code on his cart. Customers scan it with their mobile phones and pay digitally. The payment goes directly into his bank account — no coins or notes needed.
Summary: Evolution of Money
- The barter system was the earliest form of exchange; a variety of commodities were used.
- Limitations of barter led to the development of money as a common medium of exchange.
- Forms of money evolved: shells → metal coins → paper currency → digital money.
- This evolution continues with QR codes, UPI, and emerging technologies.

Barter Systems That Still Exist Today
Although money has replaced traditional barter systems globally, some barter practices persist — especially in India.
Junbeel Mela — Assam (UPSC Favourite)
Junbeel Mela (jun = moon in Assamese; beel = wetland) is a three-day annual socio-cultural fair at Junbeel in Morigaon district, Assam.
- The mela begins with Agni Puja (worship of fire) — a prayer for universal wellbeing.
- Originated in the 15th century — chiefs of Tiwa, Karbi, Khasi, and Jaintia tribal communities gathered to discuss political issues and maintain friendly relations.
- Bartering begins early in the morning with local products: roots, vegetables, fruits, herbs, spices, handmade goods, and forest artifacts.
- Hill community goods are exchanged with plains people for rice cakes and other foods that cannot be grown in hilly terrain.
- It continues to be an important socio-cultural event today.
Other Modern Barter Examples
- Book Exchange Clubs: Trading old books for new ones — no money involved.
- Old Clothes for Utensils: A vendor visits homes offering new utensils in exchange for old/used clothes or fabrics. Both parties benefit — households dispose of unwanted items; vendors collect materials to resell, repurpose, or recycle.
