How Do ‘Coins’ Stay in Circulation and Why Do Some Become Rare?

Imagine coins are like little toys. If they're fun to play with, people keep them around, but if they break easily or look old, they might toss them aside for new ones. Sometimes, a coin becomes so special that it's no longer used as money, and people collect them instead.

Coins are made to be used every day. When you buy something, like candy from the store, you give the cashier a coin, and they might give you change back in coins too. That’s how coins keep moving around.

If a coin is special or looks different from others, people might want to save it instead of using it. This means fewer of those coins are out there, making them rare.
