Neat little coin! Perhaps, at that weight, more likely a tetartemorion? Maybe unpublished? Certainly there are examples with left-facing Corinthian helmets on one side, such as:

But I've not seen one with helmets on both.
This one is kind of interesting in that it has a helmet-left on one side, and helmeted head of Athena (right-facing) on the other...I wonder if yours has a cropped-off head below that helmet in the left pic? Of course yours would be facing left.
