A lot of you were curious about stuff like why American money is green, why other countries have more colorful currency, and who decides whose picture goes on each bill. We’ll get you all those answers — and more! Plus, we’ll meet a museum’s money curator, learn about the way money art protects us from fakes and think about how we’d design our own money … if anyone asked us.

Money Talks answers

1. The Smithsonian

2. Get out a five dollar bill and look at the Lincoln Memorial on the back. If you look closely you can see the names of 26 states written across the top of the building.

3. When they were first designed in the early 1860s, we only had black and white photography. The designers chose a bright color that couldn’t be reproduced just by taking a picture. Green is also seen as a trustworthy color.

4. The banknotes that we use today were first designed in the 1920s. At the time, currency designers didn’t think about the role women played in the nation’s history. They wanted to use currency as a way to honor the nation’s Founding Fathers.
