This obverse type Crawford identifies as Roma (292/1) on the basis of comparison with this gem (apologies for poor image) which (apparently) bears the inscription AVE ROMA:
I just wanted to throw up this coin type (494/35) as well to put all three next to each other for future reference:
Notice the emphasis put on rendering Roma’s hand clutching the spear before the shield. Also notice the variation in shield designs.
Update 4/25/16:
Little did Crawford know there was a better parallel right in the BM collection (1923,0401.408). Notice the star and crescent which has become crescent and denomination mark on the denarius. Even the shield design is the same!
(Drawing is BM 2010,5006.1262)

Update 2/1/2024:
This is probably also Roma. Image from a BBC news story on BM thefts
