The history of paper money is older than most people assume. China issued the first widely circulated banknotes during the Song dynasty, almost a thousand years ago. Merchants on long trade routes simply got tired of carrying heavy strings of bronze coins, so they began depositing the coins with trusted houses and exchanging paper receipts instead. When Marco Polo described the practice to a skeptical European audience, the idea sounded fantastical. Yet within four centuries banknotes had crossed every major economy. What changed was not the paper but the institutions that stood behind it. My own grandmother kept a small tin box of 1970s Korean ten-won bills under her bed. She used to laugh that one day even those would be worth nothing — and she was almost right.
