What is the difference between a banknote and a coin in Indian law?

Two separate legal universes

Most people treat notes and coins as interchangeable forms of the same thing — money. In law they are not. They exist in two separate statutory frameworks, with different issuing authorities, different legal tender rules, and different treatment when things go wrong.

Banknotes are governed by the RBI Act 1934. They are issued exclusively by the Reserve Bank of India. Every banknote carries the RBI Governor's signature and the text 'I promise to pay the bearer the sum of [denomination] rupees' — a formal legal obligation of the RBI under Section 26(1). Banknotes can be demonetised by government notification. Banknotes carry no intrinsic material value — their value is entirely the state's promise.

Coins are governed by the Coinage Act 2011. They are issued by the Government of India directly, minted at four government mints — Mumbai, Kolkata, Hyderabad, and Noida — and supplied to the RBI for distribution. Coins are not a promise to pay. They are physical tokens of specified metal composition whose face value is declared by law. Coins carry limited legal tender up to ₹1,000 for ₹1-and-above denominations, and up to ₹10 for fifty-paise coins.

The ₹1 note — an anomaly between the two worlds

The ₹1 note is a curiosity that sits between these two frameworks. It is issued by the Government of India rather than the RBI, bears the signature of the Finance Secretary rather than the RBI Governor, and is technically a government security rather than an RBI banknote. Yet it functions as currency and is legal tender. For collectors, a genuine ₹1 note from any era — including very old issues — carries this unusual dual identity and can be a desirable piece precisely because of its historical uniqueness in India's monetary architecture.

What this means for defacement and destruction

The legal prohibition on defacing currency applies differently to notes and coins. For notes, the RBI's Clean Note Policy and the Prevention of Damage to Public Property Act 1984 govern defacement. For coins, the Coinage Act 2011 under Section 11 specifically prohibits melting, destroying, or defacing coins. The Coinage Act's prohibition on melting is particularly relevant to collectors — an old coin that has numismatic value could theoretically be melted for its metal, but doing so is a criminal offence under the Act regardless of the coin's age or the owner's intention.

What this means for demonetisation

A critical difference: coins have never been demonetised in India in the same way as notes. The 25-paise coin was withdrawn — removed from circulation — in 2011, and coins of lower denomination were withdrawn earlier. But no formal demonetisation notification under the Coinage Act has declared any standard Indian coin to be legally dead in the way that the 1946, 1978, and 2016 notifications did for notes. This means that withdrawn coins — including the 25-paise, 10-paise, and 5-paise coins — technically retain their legal status even though they are no longer in practical circulation. A collector holding a large quantity of old paisa coins is holding legally valid property with no holding restriction.

For the collector

Understanding that banknotes and coins are governed by different laws helps a collector navigate different situations correctly. Melting a coin: Coinage Act offence. Defacing a note: RBI Clean Note Policy violation. Demonetisation: only possible for notes via RBI Act. Coin legal tender limits: Coinage Act. Note legal tender: unlimited under RBI Act. The frameworks do not cross — knowing which applies to the item in your hand is the foundation of every other legal analysis.
