The Invention of Money
Long before coins existed, people exchanged goods directly, trading grain for cloth or tools for livestock. This barter system worked among neighbours but stumbled whenever two parties did not want what the other offered. To bridge such gaps, communities began accepting certain prized objects -- shells, salt, or metal rings -- as a stand-in that everyone would take. These tokens solved a basic problem: they let value be stored and carried until it was needed. Eventually rulers stamped pieces of metal with official marks, guaranteeing their weight and turning them into coins. Money thus did more than ease trade; it allowed taxes to be collected, debts to be recorded, and wealth to be measured across great distances. Its true power was abstraction -- turning a cow or a sack of grain into a number anyone could compare.
