Korean numismatic charms are small metal objects that people in Korea believe bring good luck and fortune. They are special because they have pictures and symbols on them that represent important things in Korean culture.
Imagine you are playing pretend and you want to be a princess or prince. You might wear a special necklace or bracelet that has jewels and pretty designs on it. That is kind of what a numismatic charm is like, but instead of being for pretend, people really believe they have magical powers.
The pictures on the charm can be anything from animals like tigers or dragons to special symbols like stars or moons. These things all mean something important in Korean culture. For example, tigers are thought to be strong and bring good luck, while the moon represents the feminine energy.
Some people keep their numismatic charms in their wallet or purse, while others tie them to their keychain or wear them on a necklace. They believe that having the charm with them helps protect them from bad luck and brings good things their way.
So, imagine having a little coin with a picture of a tiger on it that you carry with you all the time. You might believe that it will help you do well on a test or bring you good friends. That's kind of what a Korean numismatic charm is all about!
