How Did People Trade Before Money Existed?

Before coins, before cash, before writing, how did people pay for anything? Not with a guy trading his goat for a pot. That scene has never been found anywhere. 320,000 years ago in southern Kenya, someone carried black volcanic glass across 55 miles of changing land. 2,000 years ago in Ohio, people buried obsidian from Yellowstone, more than 1,500 miles away. In the Near East, little clay pebbles used to count grain slowly turned into the first writing. And in Mesopotamia, silver measured debt so heavily that kings had to wipe the slate clean. This is the story of how trade started not with a price, but with a relationship, and why your brain still keeps score every time a friend pays for dinner. ⏱ CHAPTERS 0:00 Paying with a promise and a rock 1:04 The black glass (Olorgesailie, 320,000 years ago) 3:11 The favor (the barter myth and the open tab) 4:59 The long road (Hopewell and Yellowstone obsidian) 7:17 The clay pebble (tokens, receipts, and the first writing) 9:06 The weighed silver (shekels, debt, and clean slates) 11:32 The open tab is still running 📚 SOURCES & FURTHER READING • Potts, Brooks et al.
