IONIA. Uncertain. Circa 650-600 BC. 1/36 Stater (?) (Electrum, 5 mm, 0.43 g). Plain surface. Rev. Rough incuse punch. Karwiese, Artemision, Type I.1 (1/24 stater). SNG Kayhan 678 (1/24 stater). Weidauer -. Very rare. Scratch on the obverse, otherwise, very fine.
The unusual weight of this coin suggests that it is actually a 1/36 stater, not a myshemihekte, which would be around 0.55-0.60 g.
