The American Dollar. I had to choose this one because there is so much hidden in our bills. On the front we have a historical person. On the back we have our seal, and the pyramid with the all seeing eye (very creepy). We also have the saying "IN GOD WE TRUST". I think our currency is pretty cool!
Mexican Peso These are very interesting notes. They have a person of history, as well as what looks to be a bull killed by a matador! Which is actually a Spanish tradition rather than a Mexican one, but, I digress.
