Can anyone ID what these are? Not really my area, but they’re interesting. I’ve seen reverse types similar to the one on the left described as a facing bust, but it takes some real imagination to see it! Feel free to share your own too!
Left coin I think is van't Haaff 13.1.1-2, attributed to Orodes II (early-mid 2nd century AD). (Note this is not the famous Parthian king Orodes II [57-38 BC]; the later Elymaean kings were related to the Parthian Arsakid dynasty but were a separate line.) That reverse type indeed started out as a facing bust; van't Haaff shows the sequence of how it degraded over time. (I should do a proper book review some time.) Right coin may be van't Haaff 10.3.2-1, "uncertain early Arsakid kings" (late 1st century BC- early 2nd century AD). Hope this helps.
Looks like @Bob L. beat me by 1 minute. On the second coin, his call may be right- the reverse types for both are extremely degraded busts, the "I" form looks kind of like something on 10.3.2-1 but that type also features some more obvious traces of the bust, while 10.4.2-4A features only lines but noe of the pictured examples features the "I" shape. As neither type is attributable to a specific ruler, I suppose it matters only to the most obsessive specialists.
