Fair to say this is a diematch?

[AETHER]

i'm confident both coins share the same obverse die, but i don't know how often engravers stuck to the same style template  on these coins. 

Am I correct this is  match?

Looks so to me.

With Roman coins the dies can be very similar but they were still engraved freehand, so if everything lines up the same - number of hair curls, position on the face, relative distance between elements - it is surely a die match. I assume the Greeks didn’t literally use a template so the same would be true. You do need a lot of points of reference to be sure, though, since they could get some things incredibly similar across different dies.
