Ionia, Ephesos(?). Circa 250-200 BC. AR Obol 8mm, 0.41 g. 

Draped bust of Artemis right, quiver at shoulder.
Forepart of stag kneeling right, head left. 

Not in SNG Copenhagen; München; von Aulock; Kayhan -; Klein -
cf CNG 75, lot 374 var. (forepart of stag left). 

While the type is similar to that of Ephesus, it is equally plausible that they were struck perhaps in Caria or Lycia.

Note: I am putting this under Ephesos under the new CNG sale
number, as Ephesos is the usual place for looking for coins
with a stag. I could not find a coin like this (without 
legends) under Caria or Lycia, nor Ephesos although does seem to be two faint letters on the left, suggesting a town of the Lycian league. DK.
