1545 CE
The Aztecs use cacao beans as currency

A 1545 document from Tlaxcallan lists the price equivalents of different items in cacao beans. For example, the value of a tomato is equivalent to one cacao bean, while an avocado was worth three, and a turkey hen was worth 100 cacao beans. The document also mentions that 200 full cacao beans equaled 230 'sunken' ones.
