Gold for thousands of years have served as a medium for monetary exchange. Gold has properties that attract people to it such as its brilliance and the fact that is so soft and malleable that it can be shaped into coins, jewelleries, etc. and because of that gold has become the most sought out metal for a long time.
Today the world gold mining output is declining because gold production has not been able to keep up with the world economies. Therefore many holders of gold store it in form of bullion coins or bars as a hedge against inflation or other economic disruptions. One way of doing this is by investing in gold at USGoldBureau.com. One can buy gold bars there. The United States Gold Bureau website has a lot of information on how to do the investing and they also have programs in which one can participate to make most out of your assets.
