While researching a coin, I found this Wiki page and found it interesting. It details the movements of Constantine's crazy kids and nephews across the empire from 337 to 361. When learning about a coin, I enjoy getting an idea of what exactly was happening at the time of its minting. This page shows, with sources pointing to more info, who was doing what and in what year. Anyway I thought others may enjoy this as well, take a look! https://en.wikipedia.org/wiki/Itineraries_of_the_Roman_emperors,_337–361
I see some research needed here to straighten me out regarding the coins issued after Julian was proclaimed Augustus in 360 and Constantius' death in 361.
