In the Aztec world, cacao was more than a drink, it was countable value. Beans could pay taxes and buy goods in markets, and some people even made counterfeit beans.
Today chocolate is a treat, but in the past it could be an economy. In parts of the Aztec world, cacao became a unit of value that people recognized and could carry easily.
For something to function as money, it should be countable, divisible, and widely accepted as a standard. Cacao beans fit some of those requirements, and demand stayed strong because the product itself was desirable.
The interesting part is how quickly a side effect of money appears: counterfeiting. Anything valuable invites imitation, and cacao was no exception, with stories of tricks that made beans look real.
It shows that money is ultimately an agreement. Paper, metal, or a bean, if society accepts it as value, exchange begins.
