Which Famous Missourians Deserve To Be On Money? [Poll]

Harriet Tubman will be coming soon to $20 bills. The Treasury Department has announced that Tubman's likeness will begin appearing on $20 bills to mark the 100th anniversary of women gaining the right to vote. 

It seems like most people agree that Tubman is a good choice, though some think that it is not fair to replace Andrew Jackson. I've heard several people suggest that maybe Jackson should stay on the $20, and a new denomination of bill be created for Tubman.

There had been a lot of discussion leading up to the announcement about which women in our country's history are deserving of such an honor. It was a fun topic of conversation. What if the Treasury Department were going to honor a famous Missourian? Who should it be?

Below are just a few suggestions (some more serious than others). Vote for your favorites, and feel free to write in anyone you think should be on money. Have fun!
