What allowed currency in the ancient world to work as a tool for the exchange of goods?

It represented an agreed-upon value

Explanation:

People were able to agree a value on a certain coin, which helped people from different parts trade with each other due to their understanding. In addition, people didn't have to barter with specific people who needed that specific product which wasn't productive and could be hard for some people who didn't produce products constantly needed. It proved to be extremely useful and productive, it's one of the reasons why civilizations were able to develop and have effective and efficient trade within their civilization and with other civilization.

explanation: we can only guess at how our actions may be perceived in the future. doing something really big like killing lots of people, saving lots of people, affecting the lives of lots of people is a sure fire way of being remembered in historical records. we can also make a difference in the history records by being a small influence on something bigger, whether that is as a civil servant, scientist or artist.

of course you could argue that we all affect history just as tiny cogs in a   bigger machine.

if you mean how do people influence our opinions of things which have already happened, then simply by writing a book which looks at things form a different perspective and trying to convince people that this perspective is more accurate or truthful. people do it all the time i.e. richard the third was a terrible or was he? plenty would disagree, it's just that their views aren't the most widely known.n:

though africans landed with few possessions, they carried their cultures, skills, and spiritual worldviews into the americas. wherever african religions took root in the new world, africans and their descendants changed and adapted their belief systems to local circumstances and influences. individual circumstances created variations in the way people practiced their faiths, what they believed, and what significance it held for their lives.
