Can you keep demonetised notes legally?

The three demonetisations and their different rules

India has had three formal demonetisations, and each is governed by different rules — or in two cases, by no rules at all.

The 1946 demonetisation affected notes of ₹1,000, and ₹10,000. No legislation was passed restricting the holding of these notes after the exchange period ended. There is simply no law that says how many of these notes a person may hold. A collector may have a hundred 1946-era notes without any legal exposure. For notes from this era that are 100 or more years old, the antiquity export restriction under the Antiquities and Art Treasures Act 1972 applies — they may not be exported without an ASI licence.

The 1978 demonetisation affected notes of ₹1,000, ₹5,000, and ₹10,000. The same position applies: no legislation restricts holding these notes, any quantity is legal, and notes that are 100 or more years old are antiquities. Given that 1978 notes are now approximately 47 years old, they do not yet cross the 100-year threshold — but within the next 50 years they will, and a collector holding 1978-era notes should note this approaching threshold.

The 2016 demonetisation is the only one with a specific holding restriction. The Specified Banknotes (Cessation of Liabilities) Act 2017, Section 5, provides that after the grace period expired, no person shall hold any specified bank note — meaning the demonetised ₹500 and ₹1,000 Mahatma Gandhi Series notes — except that a person may hold up to ten notes in total for any purpose, or up to twenty-five notes specifically for the purposes of study, research, or numismatics.

The collector exemption in full

The twenty-five-note numismatic exemption deserves careful reading. It applies specifically to notes demonetised on 8 November 2016 — the ₹500 and ₹1,000 Mahatma Gandhi Series notes. It does not apply to any other demonetisation. It permits holding up to twenty-five such notes for study, research, or numismatics — three purposes that a collector clearly qualifies under.

The exemption is a number limit, not a value limit. A collector may hold twenty-five demonetised ₹1,000 notes (face value ₹25,000) or twenty-five demonetised ₹500 notes (face value ₹12,500) — or a combination of both, not exceeding twenty-five notes in total under the numismatic exemption. The collectible market value of these notes is irrelevant to the exemption calculation. Two recent Bombay High Court judgments are important for collectors who missed the 2016 exchange window due to circumstances beyond their control. In Girish Rameshchandra Malani v. Union of India & RBI (Nagpur Bench, April 2026), the Court held that a citizen cannot be penalised for exchange deadline non-compliance caused by police seizure of the notes. In Ramesh Bapurao Potdar v. Union of India (Bombay HC, 2025), the same principle was confirmed where Income Tax department seizure in 2016 prevented timely exchange — the Court directed RBI to accept the notes despite the deadline having passed.

Holding more than twenty-five 2016-demonetised notes — beyond the ten-note general allowance — without being able to establish a legitimate numismatic purpose puts a collector in technical violation of the Specified Banknotes Act. Documentation of the collection's numismatic character, as always, is the practical safeguard.

A significant legal acknowledgement

The existence of the numismatic exemption in the Specified Banknotes Act 2017 is worth noting beyond its practical scope. It represents the one moment in Indian legislative history where Parliament explicitly recognised that numismatists exist, that they have a legitimate reason to hold demonetised currency, and that the law should accommodate them. The exemption is narrow and specific — but it is precedent. It is the foundation on which a broader legal recognition of numismatics could be built.
