Gold is an important part of Indian culture and many families invest in gold for future purposes like marriage or retirement. It is better to invest in gold coins rather than jewelry due to lower fees. Banks sell pure gold coins but at a 10-15% premium over market rates. Jewelry shops offer cheaper rates but purity should be verified for small shops. Post offices and reputed institutions also sell coins at slightly higher rates than shops. Gold financiers are another option that also provide loans against gold deposits.
