Currency developed as a way to trade with people without having to exchange goods every time. Each civilization/culture comes up with their own currency, ranging from precious objects like salt and gold to government backed standards like coin and paper.

Today, $1 in the US is still $1 all over the world, but that can be exchanged for an appropriate amount of local currency.
