What are your micronation's currencies called, and how did you design them?

Recently, I've been seeing some pretty cool currency designs (specifically from Anem and Pangeria) and I'm curious to learn more about the currencies used in the other micronations here! What are they called, and what inspired the names? Do your currencies have a unique design, symbol, or backstory? I'd love to hear how you came up with the concept and see any images of the designs if you're willing to share.
