How Did the First Coins Come Into Use?

Imagine you're a farmer who grows wheat and wants to buy apples from another farmer. You can't just trade wheat for apples every time, it would be too messy. So, people started using small pieces of metal, like coins, that could easily move from one person to another. These were the very first coins! The idea came from ancient places like Lydia, where they used a shiny kind of metal called electrum for trade.
