Bimetallic standard

Okay kiddo, have you ever heard of a penny? It's a coin we use for buying things. Now, a long time ago, people used to make pennies out of two different kinds of metal – copper and nickel.

The bimetallic standard is a way of deciding how much a penny is worth. Basically, it means that the value of a penny is determined by the amount of each metal that it contains. So if a penny is made up of mostly copper, it's worth more than if it's made up of mostly nickel.

This standard is important because it helps make sure that pennies are all worth the same amount, no matter where they are made. It's like having a recipe for baking a cake – as long as you use the right ingredients in the right amount, your cake will turn out just right every time.

So that's the bimetallic standard – a rule that helps make sure all pennies are made the same way and are worth the same amount. Pretty cool, huh?
