Watch List notes:

ASIA MINOR, Perhaps the area of Caria. Uncertain mint. Early to mid 4th century BC. Hemiobol (Silver, 6 mm, 0.21 g, 3 h). Female head to left, her hair bound in a tainia. Rev. Tamgha or monoskeles within a circular incuse. Apparently unpublished save for auction appearances. But for two pieces from the same dies as this see: Roma e100, 2022, 335 (obol, 0.42 g); CNG e346, 2015, 142 (hemiobol, 0.36 g). For the same reverse, see: SNG Kayhan 744. Very rare. Clear and darkly toned. Traces of double striking on the reverse, otherwise, about extremely fine.
