Little update: After talking with Timinator a bit I adjusted some of the font sizes and centering to make readability better. Definitely going to go with the different inlays for each denomination. I've been polling my poker players and social media and so far "The White Coat Club" is the winner. While there are a million different inside jokes and medical puns I could use on these I do like the idea of having a generalized theme understandable by more people.
