Late Roman coin with two crosses on the reverse

Hi, friends!

Can you please help me identify this coin? I can't find any reference about it in the books or online. Coin is specific due to two crosses on the reverse next to the goddess Victoria. Obverse legend: SECVRITAS REIPVBLICAE. The portrait is probably one of the emperors of Valentinian dynasty (I believe it's Valentinian II). The mint is Constantinople.

Has anyone come across with this type of coin (with the two crosses on the sides)?
 

using tesorillo.com, it looks a lot like valentinian II. other than confirming your suspicions, i cant really help.

Reverse inscription is SECVRITAS REIPVBLICAE and ruler on the obverse should be Valentinian II. DN VALENTINIANVS…

Unfortunately I can´t find your coin on OCRE either :(

Looks like already said, Valentininanus, Securitas Republicae

Mint CONSA (Constantinople  1st officina)

The crosses might be mintmarks of series or engraver marks, I guess Numista do not take in count that.

I have an example which I've tentatively identified through Helvetica's lists as Valentinianus I, Ric IX 42a-7, 367-375. Yours is much nicer than mine. 😉
