I've been working and searching on this coin of Constantius Gallus for hours. It was likely struck in Amiens. The nearest attribution is RIC VIII - Amiens- 47. Wildwinds list only 2 or 3 examples, but without the letter S in left field or even the officina BI in exergue. Denomination could also be a Centenionalis. The coin weighs 4.08 g. Diameter: 18 mm. - 19 mm. Please let me determine the exact attribution.
I also suspected Antioch at first, but there are no coins there (wildwinds) that have ANBI as mintmark sand S in left field of reverse.

Charles, Wildwinds does not have every coin, there are many examples that it does not have. Dane's collection is here. I don't have time to go through them for you, I think there are examples of Constantius II with the S. Dane might want to see an example of your coin if she doesn't have it. http://www.catbikes.ch/helvetica/feltemps.htm
Probably Antioch I would guess, could end up being a very rare type - also, nice patina on that coin.
I found an example of Constantius II with ANBI as mintmark along with the letter S in left field. But there wasn't any example of Constantius Gallus in this respect. I think my coin shows Emp. C.G. on obverse. Am I right ??
I agree with RIC VIII Antioch 149 unlisted officina. Known for AI so not really unexpected. A very nice find nonetheless.
