Ancient Greece made lasting contributions to economics, philosophy, and governance, and was one of the earliest cultures to mint metal coins for standardized exchange. However, Greece did not invent or use paper currency. Greek commerce relied on silver and bronze coinage and was part of a broader Mediterranean coin-based trading system. Paper currency did not appear in Europe until long after it had been developed in China, eventually making its way west via trade and influence over many centuries. Although Greece is rightly credited with introducing foundational concepts in democracy, mathematics, and philosophy, the realm of paper money belongs to Chinese history. Associating paper currency with Greece overlooks the chronological and technological realities of global financial development. Understanding where innovations originated helps us appreciate the diverse contributions different cultures have made to our modern economic systems.
