This is the smallest coin I own. I wasn't even sure my scale would register the minuscule weight. But the devises are engraved so well, even with the wear, there is no mistaking what they are. The coin was struck slightly off center, but in truth, I can't image how they could strike such a small flan. MYLASA, CARIA AR Tetartemorion OBVERSE: Lion's head left with reversed foreleg below REVERSE: Lion's scalp facing, flanked by leg on both sides, in incuse circle Struck at Mylasa, 392-376 BC .2g, 6mm SNG Keckman I 837-846 (lion left) I do not own this reference so am relying on internet sources. Struck by Hecatomnus of Mylasa or Hekatomnos (Greek: Ἑκατόμνος) who was an early 4th-century BC ruler of Caria. He was the satrap (governor) of Caria for the Persian Achaemenid king Artaxerxes II (404–358 BC). However, the basis for Hecatomnus' political power was twofold: he was both a high appointed Persian official and a powerful local dynast, who founded the hereditary dynasty of the Hecatomnids. In a previous thread, someone said these small coins were carried in the mouth in order to hide them from robbers. I would probably swallow it and have to search for it at a later time. Yuk! Post your small coins of any era.
