The Khoikhoi People - herders (kept animals like goats, cattle and sheep) - traded livestock for alcohol, copper and beads
The African Bushmen (San People) - nomadic (moved from place to place hunting wild animals and finding what they needed like water and plants) - self-sufficient (no need for trade or money)
Bartering - after staying in an area for a longer period of time, people wanted to trade their surplus products for other products that they needed
Some Problems with Bartering - It was difficult to determine if the value of one product, which was to be swapped for another product, was of the same value or quantity - It was difficult to find someone who wanted or was interested in what you had to offer - It was time-consuming because it was not easy to find someone who had what you needed
Commodity Money - used in the trading process - started out as shells and became metallic money when precious metals like gold, silver, bronze and copper were discovered
