The gold, on the other hand, was a materialistic thing used for exchange of goods. The gold was very highly valued, so each amount of gold had certain valuation, and according to its valuation the people were able to purchase certain goods with it. The gold was in a many ways what the paper money are in the present day.
England was the most dominant, especially with trade routes.
