Q.Collect five different kinds of currency notes and coins in circulation today. For each one of these, describe what you see on the obverse and the reverse (the front and the back). Prepare a report on the common features as well as the differences in terms of pictures, scripts and languages, size, shape and any other element that you find significant. Compare these with the coins shown in this chapter, discussing the materials used, the techniques of minting, the visual symbols and their significance and the possible functions that coins may have had.

To answer this question well, you need to observe real currency and then compare it with the historical coins described in your NCERT chapter. Let me walk you through the structure of a complete, exam-ready report.

First, collect five different denominations. For example, you might pick a ₹10 note, a ₹20 note, a ₹50 note, a ₹100 note, and a ₹500 note. For coins, you could take a ₹1 coin, a ₹2 coin, a ₹5 coin, a ₹10 coin, and a ₹20 coin. Now, describe what you see on each.

On the obverse (front) of every Indian banknote, you will find:

• The emblem of the Government of India (the Lion Capital of Ashoka).
• The words "भारत" (Hindi) and "INDIA" (English).
• The denomination written in numerals and in words in Hindi and English.
• The signature of the Governor of the Reserve Bank of India.
• A guarantee clause and the promise of the Governor.
• A unique identification number for each note.

On the reverse (back) of each note, you will see:

• A different theme or motif — for example, the Sun Temple on the ₹10 note, Ellora Caves on the ₹20 note, Hampi on the ₹50 note, Rani ki Vav on the ₹100 note, and the Red Fort on the ₹500 note.
• The denomination in numerals and in 15 other Indian languages in a language panel.
• The year of printing.

For coins, the obverse typically shows the Lion Capital and the denomination in Hindi and English. The reverse shows a different symbol for each coin — for instance, a hand showing a 'stop' sign on the ₹1 coin, a rising sun on the ₹2 coin, a lotus on the ₹5 coin, a globe with the map of India on the ₹10 coin, and a banyan tree on the ₹20 coin.

Common features across all notes and coins: they all carry the national emblem, the name of the country in Hindi and English, and the denomination. All notes are rectangular and made of paper or polymer; all coins are circular or polygonal and made of metal alloys.

Differences: notes vary in size (larger denominations are slightly bigger), colour, and the specific historical monument or theme on the reverse. Coins vary in shape (some are circular, some are 12-sided), size, weight, and the symbol on the reverse. …

Let us begin with the coins and notes you can find in your pocket today. Take out a ₹10 note, a ₹20 note, a ₹50 note, a ₹100 note, and a ₹200 note. Also pick up a ₹1 coin, a ₹2 coin, a ₹5 coin, a ₹10 coin, and a ₹20 coin. Now, turn each one over in your hand. What do you see?

On the obverse (front) of every Indian banknote, you will find the portrait of Mahatma Gandhi in the centre. To the left is a small motif — a Swachh Bharat logo or a language panel. The denomination is written in numerals in the centre and in words in Hindi and English. The signature of the Governor of the Reserve Bank of India appears below the portrait. On the reverse (back), each note carries a different theme. The ₹10 note shows the Sun Temple of Konark. The ₹20 note shows the Ellora Caves. The ₹50 note shows Hampi with the stone chariot. The ₹100 note shows the Rani ki Vav stepwell in Gujarat. The ₹200 note shows the Sanchi Stupa. Each reverse also has the denomination in numerals, the year of printing, and the RBI logo.

Now look at the coins. The obverse of every Indian coin today bears the Lion Capital of Ashoka — our national emblem — with the words "Satyameva Jayate" in Devanagari script below it. The reverse shows the denomination in numerals and in words, along with a motif. The ₹1 coin shows a hand showing a thumb — the "One Rupee" symbol. The ₹2 coin shows a map of India. The ₹5 coin shows a wheel — the Ashoka Chakra. The ₹10 coin shows a combination of the Lion Capital and the denomination. The ₹20 coin shows a lotus flower. All coins are circular except the ₹10 coin, which is scalloped (with ten sides), and the ₹20 coin, which is dodecagonal (twelve sides). The ₹1 and ₹2 coins are made of ferritic stainless steel, the ₹5 coin is made of nickel-brass, the ₹10 coin is made of bi-metallic (nickel-brass centre with copper-nickel ring), and the ₹20 coin is also bi-metallic.

Now, what are the common features across all these notes and coins? First, every piece carries the national emblem — the Lion Capital on coins, and the Gandhi portrait on notes — asserting the authority of the Indian state. Second, all denominations use both Hindi and English for the denomination, and the notes have a language panel with 15 languages. Third, the shape is standard: notes are rectangular (though different sizes — the ₹10 is 123×63 mm, the ₹200 is 146×66 mm), and coins are mostly circular except the two special shapes. Fourth, every piece has security features: notes have a security thread, watermark, and micro-lettering; coins have serrated edges or bi-metallic construction to prevent counterfeiting.

The differences are equally telling. The pictures on notes celebrate India's cultural heritage — temples, caves, stepwells, stupas — while coins use abstract symbols (hand, map, wheel, lotus). The scripts on notes include 15 languages, but coins only use Devanagari and English. The size of notes increases with value, but coins vary in size and weight without a clear pattern. The materials of coins have changed over time: older coins were made of copper, nickel, or brass, but modern coins use stainless steel and bi-metallic combinations for durability and cost.

Now, compare these with the coins shown in your NCERT chapter on early Indian history. The chapter discusses punch-marked coins from the 6th century BCE onwards, made of silver and copper. These were irregular in shape — roughly rectangular or square — and were not minted but punched with symbols using dies. The symbols included animals (elephant, bull), trees, hills, and geometric patterns. Each symbol had meaning: the bull represented strength and fertility, the elephant represented royalty and wisdom, the hill represented the cosmic mountain Meru. These coins were not issued by a single authority but by guilds, merchants, and local rulers. Their function was primarily trade — they were a medium of exchange in the growing urban economy of the Mahajanapadas. …
