We tried to be unique with our money so we made them weird shapes like triangles and arrows so people will recognize it is our money and not a different countries money.
We made these because no other money is a triangle so we were trying to be unique. We did in dust we trust because there is a ton of dust on mars and in American dollars it is in god we trust so we did in dust we trust (plus it rhymes). Finally we did Kingdom of Dustania on it because that is our country.
We did all the money in random shapes to be unique but we really didn't do anything else that unique with them though. But are 25 cent coin has a cool picture. Are coins are very different and have shapes and designs that most of you have never seen before. We tried t make things as weird and different as possible because mars is a weird place with things we don't know about. ANd we have three more type of dollars.
