Tetradrachm

Tetradrachm is like a toy money that people used to have a long time ago in a place called ancient Greece. It was made of shiny silver and was used to buy and sell things. It was also used to trade with other countries. People really liked the tetradrachm because it had a picture of their favorite gods and goddesses on it, like Athena or Zeus. It was like a special and important treasure you could hold in your hand. Today, people still collect and study these old coins to learn about ancient Greece and what it was like back then.
