This particular coin can be found with both a (gamma)SIS and a (officina)SIS Mint Mark. I think mine is the one with officina. I don't want to smooth it until I am sure. As always comments and corrections are welcome and helpful.
despite the unusual obverse legend of FL CONSTANTIS BEA C, your coin is Constans. at this time, Siscia operated five workshops-- A, B Γ Δ and Є though RIC might not have recorded examples of each, they are all possible. Yours is tough to make out...maybe B.
Thanks for the feedback. I will re-check. It looks exactly like the one shown in Wildwinds Which has what is called an (officina letter).
officina and workshop are the same thing. the example from Wildwinds looks like the third workshop-- Γ (gamma)
I very much appreciate the time you have taken. Now I need to re do my attribute. One more question. The only one I can find with gamma has a dot before and a dot after.
I wonder if that is just •SIS? Not listed here as a known combination though, only •SIS• http://finds.org.uk/romancoins/articles/page/slug/fourth-century-mints
Neither •SIS nor •SIS• is recorded for this (one standard) type, although I'll admit that it looks like •SIS in the photo. The Epsilon officina mark is often smaller than the other letters in the mint mark, and even though we write a capital E with a straight vertical line, back then the Episilon was written with a curved back, so my guess is that the mint mark is supposed to be ESIS. That would make this coin RIC 255, minted 335-336 A.D.
