Here is another coin I can't seem to find a proper identification for. A helmeted Licinius with a Trier mint mark.
On Wildwinds there are three Licinius coins very similar, but two have a PTR mint mark, and the other has the STR mint mark as on this coin. The reverse of the STR coin is completely different though.

There is a Licinius coin on Vcoins that is the same obverse and reverse, with the STR mint mark, but it has a star in the left field. It is not listed on Wildwinds. This coin does not have the star.
Obverse: LICINIVS P AVG or LICINIVS PF AVG. Reverse: VIRTVS EXERCIT. The coin is 19mm in diameter.
Any help is appreciated.
