I like Severan era As-sized Balkan AE's, but is there any way to search for them (without typing in each town)? What search term should I use? While we're at it, some others: Khrusu II. There's so many spellings. Third: AE1 size coins of Valentinian, etc.
You can search for provinces -- for the general Balkan area you have Moesia Superior, Moesia Inferior and Thracia (or Thrace).
