Unknown Eastern Roman Coin #2 [solved]

Hello all, 

I have a coin here that I believe is from the Crisis of the Third Century, though the emperor is hard to determine. The coin is around 1.2g and around 12-13mm. 

Theodosius I.

Struggling a little with the reverse, unsure if it's a cross or chi-rho.

If it's a chi-rho, it's N#125847 .

If it's a cross, it's N#451384 .

If it's a chi-rho, it's N#125847 .

If it's a cross, it's N#451384 .

Looked to be a cross upon closer inspection. Thanks!
