> Imagine if a "Bank of Italy" maintained independent northern, central, and southern notes. How would this work? I still remember before Slovenia was in the EU we had our own currency that was okay but not so hot. All big transactions between people like buying a home were done in deutsche marks. Or at least everyone talked about them using DEM and later EUR as the currency. Point being people will absolutely use the most stable currency easily available regardless of what their local currency is.
