you the better deal. One other thing that you must keep in mind when buying gold is the mark of purity that it bears. Banks in India today sell gold that carries a 99.99 per cent Assay Certification from Switzerland, which signifies the highest level of purity according to international standards. So if you were to take your gold coin bought at an Indian bank to any country in the world, you will be able to sell it with no trouble because the purity mark is internationally recognized. Smaller jewellers deal in coins that have been certified by the Bureau of Indian Standards.
