I've kinda wondered what a nock as bill would look like if it was real, so I made one, and I thought it was pretty cool, so I decided to share it. In lore, this bill represents 10 nocks (roughly equal to 75 modern day dollars), and was printed in Libertas, Eleutheria in 1930 (around the end of Iteration II). The nine stars represent the 9 GUE States, and the dreadnought is well... a dreadnought. Since there's not many iconic structures I could use from II as a monument, I figured this was the best.
I might make more notes, or hey, you could too! If you couldn't tell, it's heavily inspired by the Euro (which is a made up currency too, the only real one is the dollar)
