The U.S. has a new 20 dollar note and it's peach and green! Peach and green?! Who thought that was a good idea? Money should be pretty even if the people on the money aren't. They could have at least added more appealing colors instead.
I guess part of the reason why the Bureau of Engraving is not doing anything drastic is tradition. American money is green and black with old white men and Roman style buildings. Anything different and it would be heresy.
The Bureau just needs to forget about tradition and try something radical. See through money, holograms, primary colors, and new people would all be great things to try for U.S. currency.
If those things don't work out, then that's okay, try something different. What ever happened to the Sacagawea coins? I liked those coins, and I think other people did too. Were the coins too pretty? Were people collecting them rather than spending them? Naw. They just disappeared! May that's why the Bureau of Engraving and the Mint don't want to do anything wild anymore.
Sure there's the state quarters, where each state gets a quarter that is unique to itself, but I haven't seen any I like so far. Also, those are only coined for a limited time so people (including my mom) are just collecting these coins to own some history. People should be able to own a nicer piece of history rather than just peach coins, corn coins, horse coins, etc.
I have so many big plans for U.S. currency, I should work at the mint or something. However, being around money has its consequences as illustrated by the Discovery Channel's program on the Loomis Fargo bank robbery (almost obsolete online).
