I’m interested in learning more about the Italian city-states, more specifically the history of their currency. Any broad histories on all the states that talk about coins, histories of individual city-states and their currency, or books about one currency are fine. I’m also open to shows/movies/documentaries that accurately portray this topic.
The following is an cut and paste from my previous book recommendation on the similar topic (the coinage system of medieval Venice):
- Day Jr., William R. et al. (eds.). Medieval European Coinage, Volume 12: Northern Italy (Italy (1)). Cambridge: Cambridge UP, 2016.
Both are primarily written for specialists so that they are extensive, but the currency and monetary policy of emerging Italian commune has rarely attract due attention in otherwise good general overview books, such as Chris Wickham's Sleepwalking into a New World: The Emergence of Italian City Communes in the Twelfth Century (2015).
Expecially if you can by chance read Italian, I'd also recommend to check the article and book written by co-editors (authors) of the above-mentioned Medieval European Coinage (vol. 12), especially by Day and by Sacocci. They also write some works also in English.
