Late Roman Empire Valentinian I Siscia mint? [решено]

Greetings,

​​​​​I bought this coin recently. I know the emperors had their names in Latin on the left side on the obverse. I can't read it to confirm this is indeed Valentinian I. The reverse is better and clearly appears as Siscia Mint under the victory angel. I am having problems. The size looks correct slightly smaller than a United States dime (17.9 mm). My scale is showing 2.7 grams. I can't deduce the lettering on the reverse to the left of victory angel and right. Is this authentic (weight is off 0.1 gram from link) and, if so, what should it be catalogued? I am thinking this one but don't know what type:

Man take a look at that mint mark, gotta love it on late imperial coins.

Anyway, as far as I can tell this is one of the dozens of RIC IX 15a variants, closest I found: Valentinian I, AE3, Siscia. 364-367 AD. DN VALENTINI-ANVS PF AVG, pearl diademed, draped, cuirassed bust right / SECVRITAS-REIPVBLICAE, Victory walking left, holding wreath and palm. C over Symbol 4 in left field, S over dot in right field. Mintmark ΓSISC [symbol 1]. RIC IX Siscia 15a, type xxxviii.

Don't worry about the difference in weight, it's meaningless on hammered coin as these were hand struck not machine made. You can find some of the RIC IX 15a variants on WildWinds: https://www.wildwinds.com/coins/ric/valentinian_I/t.html

I know right . It is interesting on the mint marks with all the lettering but confusing. That points in the right direction. Thank you for your expertise as the website was much more detailed.
