Buying gold coins can be a useful way to acquire physical gold. While physical gold coins are often considered a store of value during economic uncertainty, they are also widely used for gifting and savings. But before making a purchase, consumers should verify purity, weight, hallmarking, making charges, GST, and buyback terms. For retail buyers, comparing these factors is important as they directly affect cost, authenticity, and resale value. 

Key Takeaways

  • Gold purchases in India attract 3% GST. 

  • Capital gains taxation depends on the holding period, with gains classified as short-term (taxed as per slab) or long-term (taxed at 12.5%). 

  • Buyers should verify hallmarking, weight, and seller credibility to reduce the risk of counterfeit or misrepresented products. 

  • BIS hallmarking is mandatory for gold jewellery and artefacts in notified areas, and hallmarked products can be verified through official BIS systems. 

Benefits of Buying a Gold Coin

Buying gold coins offers a convenient way to hold physical gold with clear purity, weight, and resale value. They are easier to store, gift, and liquidate than jewellery, and hallmarked coins provide better authenticity and transparency for retail buyers. 

For many buyers, gold coins also serve as a simple way to diversify savings and hold a tangible asset that can be useful during market uncertainty. When bought from trusted and authorised sellers, they can be easier to compare, verify, and resell than many other forms of physical gold. 

How to Verify the Authenticity of Gold Coins? 

To verify the authenticity of a gold coin, individuals should check the purity, weight, hallmark details, and invoice before buying. In India, hallmarked gold can be verified using the BIS Care app or BIS verification tools by entering the HUID. Additionally, the coin should also match the stated weight and purity mentioned on the seller’s bill. 

You can also compare the coin’s design, dimensions, and weight against the seller’s specifications. For added assurance, ask for documentation from a BIS-recognised Assaying and Hallmarking Centre if the coin is being tested separately. At-home tests like magnet checks are not reliable enough on their own, so they should only be used as a basic preliminary check. 

If the coin is hallmarked, look for the BIS logo, purity mark, and HUID. Older coins may not carry HUID if they were minted before the current hallmarking system, so invoice records and seller documentation become especially important in those cases.

How to Check the Weight and Hallmark on Gold Coins? 

Check the packaging or invoice to confirm the coin's weight; if possible, use a calibrated scale. Next, search for the BIS hallmark details, such as the BIS logo, purity mark (such 999 or 916), and, if relevant, the six-digit HUID. HUID may not be present on all legacy coins, even if it is necessary for hallmarked gold. Compare these details with the seller's certificate and purchase invoice for confirmation.

Things to Keep in Mind When Buying Gold Coins 

If you’re planning to purchase gold coins, you need to be aware of certain key factors. This will help you make a well-informed purchase decision.  

  1. Purity of the Gold Coin

The first factor you need to consider when buying gold coins is their purity level. The purity of gold is measured in Karats. Common purity levels available in India include: 

  • 18-Karat gold: 18K gold articles contains 75% pure gold and 25% other metal alloys. 

  • 22-Karat gold: contains 91.67% pure gold and 8.33% other metals, such as copper, silver, or zinc. 

  • 24-Karat Gold: Contains 99.9% pure gold and is typically preferred for coins and bars. 

2. Hallmarking 

The Bureau of Indian Standards (BIS) is responsible for setting quality standards for gold in India. BIS hallmarking of gold jewellery and artefacts has been made mandatory in a phased manner across notified districts, and only hallmarked gold can be sold in these areas. Hallmarking certifies the purity and fineness of gold through BIS-recognised Assaying and Hallmarking Centres. 

3. Weight of the Gold Coin

Gold coins are manufactured in a wide range of denominations, starting from as little as 0.25 grams to as much as 100 grams. Generally, most individuals tend to purchase 1-gram gold coins.  

However, if you’re looking at gold coins as a way to invest idle funds, it is advisable to opt for the highest possible denomination. Opting for lower denominations would mean having to deal with multiple coins, which can make securely storing them challenging.  

4. Making Charges 

Making charges refer to the cost of manufacturing the gold coin. For gold coins, these charges are usually lower than for jewellery and may vary depending on the seller, brand, and packaging.  

In some cases, minted coins may carry minimal or fixed premiums instead of percentage-based making charges. Buyers should compare the total cost (gold price + charges + GST) before purchasing.  

5. Certificate of Authenticity 

Gold coins are sold by jewellers, banks, and authorised dealers. Banks may sell gold coins, but typically do not offer buyback facilities. When purchasing, ensure you receive proper documentation detailing purity, weight, and hallmarking information. 

6. Bill of Sale 

If you purchase a gold coin from a jeweller, make sure to get a proper bill of sale. The bill must contain details of the jeweller, such as the registered name of their business, GST registration number, and address.  

Furthermore, the bill of sale must also clearly specify the details of the gold coin purchased, including the weight, the current per-gram price of gold, and the purity level of gold in Karats. Having a valid bill of sale can make selling gold coins a lot easier in the future.

7. Selling Gold Coins 

Banks in India generally do not offer buyback of gold coins sold by them. To liquidate gold coins, individuals usually sell them to jewellers, bullion dealers, or gold buyers, subject to purity verification and applicable deductions. 

8. Taxation 

Gold coins are treated as capital assets under income tax rules. 

  • Short-term capital gains (STCG): If sold within 24 months, gains are taxed as per the individual’s income tax slab. 

  • Long-term capital gains (LTCG): If held for more than 24 months, gains are taxed at 12.5% without indexation. 

  • GST: A 3% GST is applicable at the time of purchase. 

Note: The 24-month holding period applies specifically to physical gold, gold coins, and digital gold. Gold ETFs, being listed securities, qualify for LTCG after just 12 months, making them potentially more tax-efficient for medium-term investors. Additionally, for physical gold sold before July 23, 2024, the earlier rate of 20% with indexation applied. 

Conclusion

Buying gold coins can be a practical way to acquire physical gold, but buyers should verify purity, weight, hallmarking, making charges, GST, and buyback terms before making a purchase. Hallmarked coins with proper invoices and documentation are easier to verify and resell. For those who prefer not to store physical gold, alternatives such as Sovereign Gold Bonds or gold ETFs provide exposure to gold without storage-related concerns.
