Why is our money green?

This week we’re tracking down answers to a bunch of your questions about why money looks the way it does. 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. P.S. We want to hear your jokes about money. Click here to send us a voicemail!
