If you peek inside a piggy bank, you will notice that coins come in different colors, sizes, and pictures.
Let's explore the easiest coin to spot first β€” the only one with a warm, reddish-brown color.

The Penny

A penny is a small coin with a distinct copper-brown color.
The front of a penny shows a side-view portrait of President Abraham Lincoln.
What about the coin sitting right next to it that looks silvery, thicker, and slightly bigger?

The Nickel

A nickel is a round, silver-colored coin that is larger and thicker than a penny.
The front features President Thomas Jefferson, while the back shows his historic home, Monticello.
How can you tell a penny and a nickel apart in a flash when they are mixed up together?
