What is the legal status of proof coins and collector coins issued by the Mint?
Proof coins and commemorative collector coins issued by SPMCIL are fully legal tender for their face value under the Coinage Act 2011. They are also numismatic collectibles sold at market prices above face value. Their legal status is dual: they are simultaneously official Republic of India coins (with all Coinage Act protections and prohibitions) and commercially sold collectible items. The GST treatment confirms this duality: 5% GST on the full transaction price including the numismatic premium.
What makes proof coins different from circulation coins
Proof coins are struck by SPMCIL's mints using specially prepared dies and polished blanks, producing a mirror-like field with frosted design elements. They are not intended for circulation — they are produced specifically for collectors. Commemorative coins mark significant national events or anniversaries. These coins are sold at prices that may be 10-50 times their face value, depending on the issue.
Despite their collectible purpose, proof coins are manufactured under the Coinage Act's authority as official Government of India coins. They are legal tender for their stated face value. The same Coinage Act melting and defacing prohibition applies to them as to any other Republic India coin — a proof ₹5 coin cannot be melted any more than a circulation ₹5 coin.
GST on SPMCIL collector coins — the government's own pricing confirmation
SPMCIL charges 5% GST on the full transaction price of its commemorative coins under HSN 9705. A coin with face value ₹150 sold for ₹5,000 attracts ₹250 in GST (5% of ₹5,000) — the GST collected exceeds the coin's face value. This is the government's own direct confirmation that numismatic coins are taxable at their full market price, not at face value. A numismatic dealer who applies the same logic — charging 5% GST on the full collectible sale price — is following the government mint's own practice.
Collecting and reselling proof coins
There are no restrictions on collecting, holding, and reselling SPMCIL proof coins. A collector who buys a proof set from SPMCIL at ₹5,000 and later sells it at ₹15,000 has made a taxable capital gain of ₹10,000. The income tax rules for capital gains — 24-month threshold, indexation for long-term — apply exactly as for any other numismatic coin. The Coinage Act's melting prohibition applies — the coins should never be melted — but beyond this, proof coins are freely collectible and tradeable assets.
