My Very Own Pawn Shop

Recently there was a news article on jewelry. In the article it stated that jewelry in some countries was still used as a means of trading, for example people would trade gold for milk or something like that. Although I came to wonder why don't they just go to a pawn shop to do that? Because a pawn shop takes everything from tires and rims to mother's rings, heck they will even take dentures I bet. So hey maybe I should go to those third world countries and put a pawn shop there. Although those countries are dangerous and I don't want to die.
