I recently came across a mention of this in a text on literature. By the way, I often find answers to these questions in scientific works. I was looking for this information because I had to write a research paper. So I searched for it through reviews of the best research paper writing services. I read them on papersbattle.com and chose. But among the used letter I came across one of the copies of the description of such and similar banknotes. I hope to publish my research work and be useful to someone.
