From last 20 years, I am keeping these coins with me. It is one of my hobby to collect coins. Their cost varies from few Indian rupees to several US Dollars. Most collectors already have some of these coins. But sometimes you find a coin so rare that in international market, you can sell it in more than $1000. So, if you have some rare coins first check out its cost online and how rear actually your coin is before selling it to anyone.
