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!
