Copper was a choice metal due to its availibilty in the Katanga region. Katanga crosses
have been used for centuries as a form of
wealth used in trade and dowry payments.
One cross = 5-6 chickens, 2 lengths of cloth,
or 6 small axes. Four to six crosses = 1 goat.
Fourteen crosses = bride dowry (the crosses had
to be returned to the brideís family if the marriage failed).
