It was the Barter which was gradually replaced with coins
made of gold and silver. In ancient times, before coins were made, people used
the barter system in where they are exchanging goods to be able to get what
they need without the use of money.
Barter simply means swap.
For example:
A person will give another person a bucket of fish in exchange of a sack of
rice.
Prior to the creation of gold or silver coins, it was the barter system that
ruled the life of our ancestors.
