This Look Familiar To Anyone?

@lou, just spitballing here, but I wonder if this wasn't originally from The Elymais Kingdom. As you likely know, the copper Drachmae sometimes (e.g. Orodes III) have a frizzy-haired, front-facing bust with an anchor to the right. The reverse is a just a series of peck marks. Something like this:

Of course, this one would have been sanded down from roughly circular to this interesting triangular shape. I'm hoping someone else will weigh in with a better answer because I have pretty low confidence that I'm correct.

Pretty good spitballing ... I'll be surprised if a better ossibility comes in.
