ELI5: Explain Like I'm 5

Numeira

Numismatics is the study of coins and money. It’s like collecting stickers, but instead of stickers, we collect coins from all over the world! Numismatists study the coins and learn about their history, how they were made, and why they are important. Some coins are very old, even over 2,500 years old! Collecting coins can be a fun hobby and a way to learn about different cultures and history.
