How Did ‘Coins’ Become a Standard of Value in Trade?

Coins are like magical pieces of money that people used to trade things long ago. Imagine you have a shiny gold coin and want to buy an apple. The coin is so valuable, it feels like magic! People started using coins because they were easy to carry and didn’t break easily, just like how we use paper money today.

Coins are made of metal, which doesn't rot or disappear like food does. That means you could save your coins for a long time and still trade them later. People also liked the way they looked, so using coins became something everyone agreed on.
