Identification Help Needed: Odd Little Greek (?) Bronze, Ae15-Ae16, Figure Standing On Prow?

I thought this one might be easier to identify based on the design but no such luck.

Seems to be a legend going around something in a more or less square pattern - a figure standing on the prow of a galley? An altar? Some sort of weapon? There is a circular border around the whole thing.

The other side is pretty much gone, with the exception of a well-defined squiggly line, for lack of a better term.

If I could only read the legend that would help but the letters are too indistinct for me and the bottom part is slightly off the flan.

Quite a chunky coin for its size, 15.3mm but 3.4mm thick and a solid 4.3 grams.

The photos came out a bit rough, it's a little clearer in hand.
