So I do have a version that I completed a few months ago (on my blog here) that might be worth publicizing. I do have a second article I plan to do hopefully once things calm down/stabilize here on more "how to make money"/"how to make security documents", but we can start with a short intro article, if desired.
"As you develop a conworld or concountry, a natural progression might be to design your own money. Banknote design, though, can look daunting at first, with a lot of interlocking parts. In the first of this series, I'll go over some of the steps in banknote design, including things to consider as you're preparing to make it rain (in whatever currency units you use)."
