I received this coin in a lot of Greek silver fractions. I've been able to ID most of the coins in this lot, and all the others were from Asia Minor, so I assume this one was, too. AR tetartemorion or 1/96 stater? ca. 5th century B.C. Obv: Head (facing right?) Rev: (Barely grain?) incuse circle. 4.5 mm, 0.20 g I've never seen an incuse barely grain before. Anyone have any guess what this might be?
I have no idea, sorry to say. But I too have an "unknown" that has what might be an "incuse barley grain." It sort of reminded me of your post, vaguely: 1.2 grams
