Roman or Byzantine [opgelost]

Hello experts 

Any chance to get the ID for this coin 

Thanks 

Byzantine

Did a search on our catalog, your coin is one of these: https://en.numista.com/catalogue/index.php?e=byzance&r=bust+right&st=all&cat=y&im1=&im2=&ru=&ie=&ca=3&no=&v=10&a=&dg=&i=ANNO&b=&m=np&f=&t=&t2=&w=&mt=&u=&g=

We know that the bust is facing right and there's ANNO on reverse, and there's some Justinian I coins on the search that fit the description, but which one…

I don't have any certainty to say that.

Thank you for help 

Waiting for another opinions on it.

I think is this one. Bcs the reverse isnt the conventional “ANNO”, its “ANN”,  and the year its “XXI” or more, and this is the only that matches in your catalog that have year 21 and the “ANN”
