Iron and copper can both be worked at relatively low temperatures. Many cultures
have used these metals as payment, with each culture choosing a distinctive form
that usually indicates the high quality of the metal. In addition, considerable
skill was required to fashion many of these objects-an aspect which made them more
useful as a desirable form of payment.
So-called "pennies" of the Kissi
tribe, Liberia (early 20th century). The twisted and hammered iron rods with
distinctive ends show that the metal can be worked in four different ways and is,
therefore, of high quality. These rods circulated interchangeably with European
forms of money.
Iron "hoe" money of the Makai
tribe, Cameroon (early 20th century). African money frequently came in shapes
reminiscent of the tools and weapons into which it could be made.
Miniature iron axes of the Fang tribe, Gabon
(early 20th century). Thousands of these "axes" were paid by husbands to the
families of their brides.
