The tetartemorion of Mylasa arrived today. Haven't taken a pic of it with the Ptolemy hockey puck yet, but this image gives you an idea of the size. It's remarkably well centered for a tiny fractional. Tiniest partridge on a coin...
The larger coin was holed to use as a necklace. The smaller coin fits through string hole of the larger coin. The larger coin is from Olbia, 404-380 BC, cast AE 100.19g 67mm Obv: Smiling gorgoneion, tongue protruding, hair as pairs of half circles, eyebrows prominent. Rev: ΑΡΙΧ; Eagle right clutching dolphin right. Same mold as SNG British Museum Black Sea #383 ex-Stack's / Coin Galleries, auction, December 2009, lot 47 The smaller coin is Ionia, Magnesia. 5th Century BC. AR Tetartemorion (0.15 gm, 5mm). Obv.: youthful head (of Apollo?) right, [M-A]. Rev.: ΓNH, bull butting right over maeander pattern. SNG Kayhan 399 var. (without reverse legend). Cf. Hauck & Aufhäuser 19 (2006), 121. The hole has a patina, but a different patina than the rest of the coin, suggesting it was made into jewelry after the ancient period. The smaller coin is said to be rare but perhaps the metal detector is changing that. It is missing in the major collections but available on the market. Eight specimens on acsearch.com are described as tetartemorions. Five more described as hemiobols.
