Can you send coins via India Post — are there weight or material restrictions?
Yes — coins can be sent via India Post. Coins are explicitly named alongside currency notes in the mandatory insured-article rule. They must be sent as insured articles. They present specific packaging challenges — heavier than notes, can puncture envelopes, can damage other articles and postal machinery if inadequately packaged. Weight limits by service type are generous for most numismatic shipments. The Coinage Act's melting and defacing prohibition is not triggered by postal sending.
The mandatory rule applies to coins equally
The India Post rule that requires insured-article classification for currency notes applies equally to coins — the provision lists 'coin' alongside 'government currency notes or bank notes.' A collector sending rare Republic coins, proof coins, or historical pieces by ordinary unregistered post is violating the postal classification rules for that category and faces the same ₹1,000 maximum compensation ceiling on loss as a note sender using uninsured Speed Post.
Weight limits and correct service
Speed Post accepts articles up to 35 kg for domestic delivery — far in excess of any realistic numismatic coin shipment. Coins should be sent as Speed Post parcels with insurance, not as letter post or registered letters. Coins in standard paper envelopes create physical problems: they press through the envelope material, can jam sorting machinery, and can injure postal workers. Every coin shipment must be sent as a padded parcel with rigid internal packaging.
Packaging — the essential requirements
Each coin should be individually wrapped in a coin flip, coin capsule, or acid-free tissue to prevent contact scratching between coins. Wrapped coins should be placed in a rigid container with foam padding on all sides — the container should not allow any movement of the coins. The rigid container goes into a corrugated outer box or padded outer envelope with all seams taped. Test: push any face of the outer packaging. If it flexes, the inner protection is inadequate.
For high-value proof coins or rare historical pieces, the packaging materials cost ₹30-80. Against a coin worth ₹5,000 or ₹50,000, this is not a cost — it is basic preservation discipline.
The Coinage Act and the Antiquities Act intersection
The Coinage Act 2011 prohibits melting, destroying, or defacing currently circulating Republic of India coins. Posting a coin does not melt, destroy, or deface it — no Coinage Act provision is triggered by postal transmission. For historical coins — British India, Mughal, princely state — the Coinage Act does not apply. The Antiquities and Art Treasures Act 1972 applies to items 100 or more years old: it restricts export outside India but not domestic postal movement. Sending a pre-1925 coin from Mumbai to Delhi by insured Speed Post does not require ASI permission or any special clearance.
