Thanks Isleño for the currency tutorial; this was exactly what I needed all those years! I designed some banknotes for another project between 1998 and 2000 using a program called Pagemaker (which I don't believe exists anymore), but after that I never got the hang of it again, until now.
The unusual amount of 70 Vargu is explained by the facts that Řots uses a duodecimal counting system and that with notes of 10, 30 and 70 one would need max. three notes to get 20, 40, 50, 60, 80, 90, Ѧ0 and Ѣ0. This system of course has some disadvantages as well, but the people of Řots are used to it.
The other banknotes will have to wait though; between 27/7 and 2/8 I will be in Canada, with limited access to my geofictional stuff. On the other hand, if you live in or nearby Montreal (and possibly also Ottawa) and don't find it utterly weird to meet with a complete stranger to discuss e.g. some bilateral relationships between our countries, you can send me a message.
Du lundi 27/7 au dimanche 2/8 inclus, je serai en vacances au Canada, donc si tu/vous habites/z à ou près de Montréal (et probablement aussi Ottawa) et ne penses/z pas qu'il soit complètement bizarre de rencontrer un parfait inconnu afin de parler par exemple des relations bilatérales entre nos pays, merci de m'envoyer un message.
