ASIA MINOR. Lycia (?). Uncertain mint. 4th-3rd centuries BC. Half chalkous (Bronze, 8.5 mm, 0.70 g, 5 h). Male head to left, hair bound with tania - perhaps Apollo. Rev. Key-like symbol formed out of a horizontal three bar sigma (?) attached to a large, slightly oval annulet. See Naumann 99, 2021, 110 and Saint Paul 12, 2017, 36, otherwise unpublished. The finest of the three known examples. A most enigmatic coin with an attractive dark green patina with earthen highlights. Nearly extremely fine.

For a vaguely similar symbol, see the obverse of the stater of Etenna that appears here as lot 203, below.
