Need Help Determinign Authenticity of This Domitian Roman Denarius

Hello, (and please ignore the typo in the title)

I acquired this coin in a group of authentic AE coins, and have unsuccessfully proven its authenticity (I know very little about silver coins). My cheap scale (without decimal points) provides a weight of 4 grams and it has a diameter of 19mm. Attached are images of the edges as well. Someone told me the portrait looked off, but I still can't come to any conclusions. Any information is greatly appreciated.

Hello and welcome. It looks fine; but now all I kind think about is the typo!

 

I agree with @Victor_Clark

My example, different date


DOMITIAN
AR Denarius
OBVERSE: IMP CAES DOMIT AVG GERM P M TR P VIII, laureate head right
REVERSE: IMP XIX COS XIIII CENS P P P, Minerva standing left holding spear
Struck at Rome, 88-89 AD
3.3g, 19mm
RIC 670

 

It's perfectly fine.

 

Thank you for the input!

 

I think it's authentic too
