Besides the dispute over Armenia, Shapur III seems to have clashed with the Alchon Huns to the east; coinage indicates that the Alchon Huns seized Kabul from him sometime before 388. They duplicated the same coin mints issued by Shapur III, with the only difference being the newly added Bactrian inscription "αλχοννο" ("alxanno"), added to display their takeover of Sasanian territory. The loss of the city was a major blow, as it had been a center of coin manufacture since the 360s.
