How did gold become the universal currency?
Yes, please.
The earliest known use of gold as currency was in ancient Egypt around 2500 B.C. The Egyptians used gold bars, called 'shat', to facilitate trade. Then, in China, around 546 B.C., gold coins were used as a form of currency. Over time, other cultures followed suit and gold became an accepted form of payment across different borders and cultures.
