While gold is a precious metal, salt was essential for survival in many parts of Africa. It preserved food, seasoned meals, and was even used as currency in some regions.

Here's why salt was so valuable:

* Scarcity in many regions: Africa has vast deserts and semi-arid regions where salt is scarce.

* Essential for survival: Salt prevents dehydration, helps with digestion, and preserves food.

* Used as currency: In some areas, salt was traded directly for goods and services.

So, while gold might be more valuable in the modern world, in many parts of Africa's history, salt was just as important and valuable.
