It is fascinating and almost magical how money appeared on our planet. Unlike most developments we enjoy, which can be traced back to a source, civilisation or inventor, money appeared in places then unconnected all over the world in a remarkably similar way. Consider the American Indians using Wampum, West Africans trading in decorative metallic objects called Manillas and the Fijians economy based on whales teeth, some of which are still legal tender; add to that shells, amber, ivory, decorative feathers, cattle including oxen & pigs, a large number of stones including jade and quartz which have all been used for trade across the world, and we get a taste of the variety of accepted currency.
