Watch List notes:

GREEK COINS
ASIA MINOR

Southeastern area, around Cilicia but not necessarily Cilician. Uncertain city. Obol (Silver, 10mm, 0.61 g 6), dated Seleucid year ΘΚΣ = 229 = 84/3 BC. Horizontal crescent, with its horns upwards, over a vertical thyrsos. Rev. Club downwards, dividing ΘΚ-Σ. Apparently unknown and unpublished. A fascinating and enigmatic coin. Nearly extremely fine.

At the present point there is almost nothing that can be said about this coin! Its date, which is presumably Seleucid, places it in the first quarter of the 1st century BC and should localize it as having been struck at a mint somewhere in SE Asia Minor (it does not look particularly Levantine, which would be another possibility for a dated coin like this).
