There is a gold mine in the US with more gold in it. Think its in Nevada. A friend of mine's family member works there.
I don't think a gold mine counts. You can technically say that all the gold in the ground is the biggest collection of gold Please Register or Log in to view the hidden image!
I thought it was going to be harder. They showed it on the Travel Channel, the workers handling the mostly foreign gold were wearing metal shoes, so the 28 lbs goldbars wouldn't break their feet if they drop them.
