VRBS ROMA, two soldiers, one standard

[Per D]

Hi all,

I'm trying to attribute this little coin, without much success as thick patina and corrosion makes it difficult to read the mintmark (it looks like four letters, possibly beginning with "SM").

I hope the style of the bust, and the circle on the standard can serve as clues for someone more knowledgeable.

It looks like Heraclea

Thanks, Victor!

(That must've been a speed record.)
