Wise collection of Gold coins

One of my friends has a habit of buying gold coins at regular interval. He started buying gold coins when gold was costing Rs 4500 per 10 gm. He has collection of more hundred coins. Most of his gold coins have weight of 10 gm. Today his gold is worth Rs 25 lakh whereas he sent only Rs 10 lakh to buy this gold. His habit of buying gold coin has paid him well and his money has increased many times. Recently, he bought Rs 30 Lakh house by selling these gold coins; otherwise, it was very hard for him to buy such a big house. We all can also get help of good returns by gold by investing money in gold. Gold value is likely to increase many times in near future too; therefore, people can expect more good returns from gold investment.
