5th century but who? (Victoria AVGG)

[Peter G5]

Dear Colleagues,

Please provide me votes on this dwarf coin (~11 mm, 1,4 gramm), relative thick compared to its diameter.
I think, he was bearded, which depicted as a stronger line on his lower jaw.
Which emperor was he?
(The obverse has loose spaced text "...P F AV...", so I would exclude the long named aspirants like Valentinianus)

Big Thanks in advance,

[Poemenius]

Honorius Rome RIC 1357
