Identification help please - Double headed axe?

[Connect4]

I have assumed that this coin is Thracian.  However, it doesn’t match other examples.
Obv. Double headed axe with S symbol is each quadrant.  Rev. Horse standing right. 
Have I misidentified the obv. as an axe?
4.6gr  16.6-17.4mm axis 12hr
Thanks

Hi C4,

I don't think it is a double-headed axe. I think it is a trident.

There are AE coins form Mylasa that fit that description, but they are much smaller (about 11-13 mm). Also, the horizontal bar on your example is very thick. Perhaps yours is a barbarous imitation?

Here is a link:

Thanks Meepzorp, very wide horizontal bar.  Great match.

The coin is in fact from Mylasa in Caria: http://hno.huma-num.fr/browse?idType=319
