Extra questions & answers
What is the barter system?
It is a way of exchanging goods and services directly for other goods and services without using money, the earliest form of exchange.
What is meant by a double coincidence of wants?
It is a situation where two people each have exactly what the other wants and are both willing to exchange them directly, which is often hard to find under barter.
Why is a common standard measure of value needed?
Without one it is difficult to compare the value of one good against another and decide a fair proportion for exchange, so one party may feel the exchange is unfair and refuse it.
What problems of barter does the farmer's story show?
The need for a double coincidence of wants, the lack of a common standard measure of value, and the problems of divisibility, portability and durability.
What are the basic functions of money?
It serves as a medium of exchange, a standard of deferred payment, a store of value, and a common measure that lets the value of goods and services be compared.
What were ancient Indian coins like?
They were made of precious metals like gold, silver and copper or their alloys, called karshapanas or panas, and bore punched symbols called rupas.
When and where was paper money first used, and when did it reach India?
Paper money was first used in China and was introduced in India in the late 18th century.
Who controls the issue of currency in India today?
The Reserve Bank of India (RBI) controls the issue of currency, and it is not legal for anyone other than the RBI to issue currency.
What new forms of money are used today?
Intangible digital money in electronic form, used through debit cards, credit cards, net banking and UPI, often via a QR code scanned with a mobile phone.
Give an example of a barter tradition that still survives.
The Junbeel Mela, a three-day annual fair at Junbeel in Assam, where tribal communities still exchange produce and goods through barter.
LET'S EXPLORE
Imagine that you are a farmer and that people use a barter system where you live. You need a whole variety of things—a pair of new shoes, a sweater, and medicines for your grandmother. But you only have an ox that you can spare. How would you be able to exchange the ox for all the different things you need from different people or places?
You would not be able to exchange the ox directly for all three things at once easily. You would have to look for someone who wants an ox and can give you something you can then re-exchange. For example, you might first exchange the ox for several bags of wheat with a trader. Then you would carry that wheat to different places and bargain separately — a part of the wheat for shoes from a shoemaker, another part for a sweater from a weaver, and another part for medicines from a chemist. Each step needs a separate negotiation about how much wheat equals each item.
What difficulties are you likely to face?
You would face the problems of the barter system: finding someone who wants an ox and has what you want, deciding a fair exchange rate without a common price, not being able to divide the ox into smaller parts, carrying heavy wheat bags everywhere, and not being able to store wheat for long because it can rot or be eaten by rats.
THINK ABOUT IT
What are the different types of difficulties you encountered in the situation above?
The difficulties are: 1) double coincidence of wants — needing a person who has what you want and wants what you have, 2) lack of a common standard measure of value — no agreed price to compare an ox, wheat, shoes or medicines, 3) indivisibility — you cannot cut an ox into pieces to pay for just a sweater, 4) portability — an ox and bags of wheat are hard to carry, and 5) durability — wheat cannot be stored for long.
In the farmer's story, imagine he finds someone who is willing to trade a pair of new shoes, a sweater, and medicines—all in exchange for his ox. Do you think it would be easy to come across such a situation?
No, it would be very rare and difficult. It is unlikely that one single person would have exactly those three different goods ready in the right sizes and quantities and at the same time need an ox. This shows why double coincidence of wants makes barter very inconvenient for everyday needs.
THINK ABOUT IT
What are the instances of double coincidence of wants in the above example?
Instances are: the farmer wants shoes but the shoemaker may not want an ox, he wants wheat; the farmer wants a sweater but the weaver may want medicines, not an ox; the farmer wants medicines but the medicine seller may want grain, not an ox. In each case both sides must want exactly what the other offers at the same time, which often does not happen.
Even if there are two people who want each other's goods and are also willing to make an exchange, other issues could arise—in what proportion should the two goods be exchanged? In such cases, it becomes difficult to compare the value of one good against another. If one of the people feels that the exchange is disadvantageous, they would not be interested in the exchange. This is because there is no common standard measure of value. In the situation given above, what are the cases where you could encounter the lack of a common standard measure of value?
You would encounter it when you try to decide how many bags of wheat equal one pair of shoes, how many bags equal one sweater, or how many bags equal medicines. Without money there is no common price in rupees to compare. How much of an ox equals a sweater? There is no agreed scale, so long bargaining is needed and one party may feel the deal is unfair and refuse.
THINK ABOUT IT
What are the different ways in which money would make the above situation easier for the farmer?
Money would help in many ways: 1) It solves double coincidence — the farmer can sell the ox for money to anyone who wants an ox and then use that money to buy shoes, sweater and medicines from different sellers. 2) It provides a common measure of value — every item has a price in rupees, so comparison is easy. 3) It is divisible — the farmer can pay the exact price for each item instead of giving a whole ox. 4) It is portable — coins and notes are light and easy to carry, unlike an ox or wheat bags. 5) It is durable — money can be stored for a long time without rotting and used later, so it acts as a store of value.
LET'S EXPLORE
The illustrations above show you some of the ways in which people practise barter today. Have you observed similar practices in your locality?
Yes, similar barter can still be seen. For example, vendors come to homes offering new steel utensils or plastic buckets in exchange for old clothes, or children in school organize book-exchange clubs where they swap story books. In some villages, farmers exchange grains for vegetables from neighbours.
What are the types of experiences people have in this process?
People often find the experience useful and friendly. Households can get rid of things they do not need and get something useful without spending money, and it helps recycling and reusing. Children enjoy getting new books to read. At times they face bargaining difficulties — debating what quantity is fair — but overall it builds community cooperation and saves money.

Will you request the shopkeeper to allow you to make the rest of the payment later?
You could request it, and if the shopkeeper knows and trusts you, he may allow a deferred payment and let you take the book now and pay

LET'S EXPLORE
The coins shown in Fig. 11.12 were found during excavations in Pudukkottai in Tamil Nadu. Their heads embossed are those of Roman kings. What conclusions can we draw from such a finding?
Finding Roman gold coins with Roman kings' heads in Tamil Nadu shows that ancient South India had strong maritime trade links with the Roman Empire. It suggests that Indian merchants exported goods like spices, textiles and beads to distant lands and received foreign coins in return. The fact that Roman coins are found in large numbers also suggests trade was favourable to India and that foreign coins were valued and circulated beyond their home kingdom.
LET'S EXPLORE
Organise yourselves into groups of five students each. Take up a group project to collect old coins from family members, neighbours, shopkeepers, and so on. Document their various features—what are they made of, what is the year inscribed on the coins, what do you observe on the obverse and reverse sides of the coins. What can you guess from your observations?
For this project, collect coins of different denominations and years and note their metal and colour. Older Indian coins were often made of copper, bronze, or silver alloys, while modern circulating coins are made largely of iron alloyed with materials such as chromium, silicon, and carbon (ferritic stainless steel). Arrange them by year to see how the size, metal, and design have changed over time.
How would you know if your guesses are true?
You can verify your guesses by comparing the coins with information from reliable sources like the Reserve Bank of India website, museum catalogues, or history books, and by asking teachers or elders who remember older currency. You can also check the mint mark, the text in Hindi and English on the coin, and reference books on Indian coinage to confirm the material, year and meaning of the symbols.

What do you think happened as coins began to be used for all types of exchanges, whether to buy vegetables or to buy some land? What problems could have come up?
As coins were used for both small and very large purchases, new problems appeared. Buying cheap vegetables needed only a few coins, but buying land needed thousands of coins, which were heavy to carry, difficult to count, and risky to transport and store safely. There was also risk of theft and the need for secure storage. This inconvenience led people to look for a lighter alternative, which was paper money for higher denominations, while coins continued for small values.

Look at a 50 and a 100-rupee note. Can you identify the motifs depicting India's cultural heritage on the reverse side of the notes? Find out more about them.
Yes. The
Feel the surface of the notes. What special features of currency notes help visually impaired persons to identify the notes' denominations?
Currency notes have tactile features made by intaglio printing that is raised to touch. Along the left and right edges there are raised bleed lines — different numbers of lines for different denominations — and raised identification marks such as a triangle, circle or diamond. The notes are also of different sizes and colours, and the raised print helps visually impaired persons feel the denomination by touch.
Questions and activities
1. How does the barter system take place and what kinds of commodities were used for exchange under the system?
The barter system takes place by directly exchanging goods or services for other goods or services without using money. For example, a student who has an extra eraser can exchange it with a classmate who has an extra pencil. Historically people used commodities that had everyday value, such as cowrie shells, salt, tea, tobacco, cloth, cattle like cows, goats and horses, seeds, red feather coils, stone discs and copper tools.
2. What were the limitations of the barter system?
The main limitations were: double coincidence of wants — both persons must want what the other has at the same time; lack of a common standard measure of value — no common price to decide fair exchange ratios; indivisibility — large items like an ox cannot be divided for small purchases; portability — goods like cattle or grain are heavy to carry; and lack of durability — goods like wheat rot or can be eaten by pests and cannot be stored long.
3. What were the salient features of ancient Indian coins?
Ancient Indian coins were called
4. How has money as a medium of exchange transformed over time?
Money began as commodity money like shells and beads, then became metal coinage around
5. What steps might have been taken in ancient times so that Indian coins could become the medium of exchange across countries?
Rulers ensured strict control over minting to keep weight and metal purity reliable, so foreign traders trusted the coins. Powerful kingdoms encouraged trade, and merchants carried Indian coins along maritime routes to places like Kerala, Tamil Nadu and overseas, where discoveries of Roman coins in India also show two-way exchange. Using strong, recognizable symbols and maintaining consistent denominations helped coins from strong Indian kingdoms be accepted in other kingdoms and countries.
6. Read the following lines from the Arthaśhāstra. “An annual salary of 60 paṇas could be substituted by an āḍhaka of grain per day, enough for four meals…” (One āḍhaka is equal to about 3 kg) What does this indicate about the value of one paṇa?
One year has
6. The fine for failing to help a neighbour was 100 paṇas. Compare this with the annual salary. What conclusion can you draw about the human values being encouraged through this?
An annual salary was
7. Write and enact a skit to show how people may have persuaded each other to use cowrie shells (or other such items) as the medium of exchange.
A simple skit: Two villagers argue about exchanging wheat for pots without a fair rate. A third person picks up smooth cowrie shells and says, “These shells are small, shiny, light to carry, do not rot, and everyone likes them. Let us agree that ten shells equal one pot and five shells equal one bag of wheat. Then we can all trade easily.” At first people doubt, but when they try, they find they can sell wheat for shells and use shells later to buy pots or fish without needing the potter to want wheat. Everyone agrees to accept shells because others accept them, and soon the whole market uses shells as money.
8. The RBI is the only legal source that prints and distributes paper currency in India. To prevent illegal printing of notes and their misuse, the RBI has introduced many security features. Find out what some of these measures are and discuss them in class.
The Reserve Bank of India uses many security features on notes: a watermark with Mahatma Gandhi's image seen when held to light, a security thread that appears as a continuous line, latent image that shows the denomination when tilted, see-through register where the front and back print align, optically variable ink that changes colour, micro-lettering, raised intaglio printing for the portrait and for tactile marks for the visually impaired, and unique serial numbers. These make copying very difficult and help people verify genuine notes.
9. Interview a few of your family members and local shopkeepers, and ask them their preferences in making and receiving payments—do they prefer cash or UPI? Why?
In interviews, many shopkeepers like Krishnappa with a fruit cart prefer UPI and QR codes because the payment goes directly to their bank account, they do not need to give change, and it is quick and safe. Some older shopkeepers and family members still prefer cash because they are used to it, it works without internet or a phone battery, and they can see the money immediately. Most younger people prefer UPI for convenience, speed and record-keeping, while some prefer cash for small payments or when network is weak. Preferences depend on ease, habit, trust in technology and network access.
