I got a 5g gold coin as a gift. I want to know how much money will I get if I try to sell it in the ‘market’ in Hyderabad. I think, I can get the Mumbai price from here http://www.moneycontrol.com/commodity/gold-price-in-mumbai.html and then should I put a 5% fees which I will lose? What are the ground realities while selling such stuff?
