How Did Paper Money Originate?

Paper money started with people using paper instead of coins. Long ago, people used coins made of metal or even shells to buy things. But one day, someone had the idea: what if they wrote on a piece of paper that it was worth as much as gold? That’s how paper money began, it was like getting a promise from the king or the government. People trusted the paper more than coins because it was easier to carry and use.
