Most coins from Gordian III carry the same countermark, which can hardly have 
served as a denominational mark judging from the range in size and weight of 
coins on which it can be found. Similar countermarks were applied also at 
Ninica-Claudiopolis and Tarsus. Contributed by Henrik Agndal, May, 2003.
