Howego writes at 781 that due to the paucity of evidence he would treat each of these delta
countermarks as individual listings. It seems to make sense that coins that were not heavily worn were
countermarked to assign a value if the issuing city was different than the city where the
countermark was
applied. Hence coins issued from NadI that exhibit the delta and NIKO (meaning that the 2
countermarks were
applied to assign a value and demonstrate whose authority
certified this value) are worn to the point of approaching slugs. These two
countermarks were
applied to other worn coins from neighboring cities, as we have seen in the past, if they were very worn. The delta on Jochen's coin above suggests to me that it was
applied by a different city to certify the value at 4
assaria. Hard to tell where. Probably in
Thrace but I wouldn't rule out
Asia Minor. I have an example from
Pautalia in my
collection as well as one from
Hadrianopolis; both
Severan. I attached the one from
Pautalia; I can't find an image of the
Hadrianopolis. Jochen's coin is interesting because it is from NadI and it can be dated post
Gordian III. The punch used seems to be round and not triangular. Cool coin Jochen!
