GREEK COINS
Kings of Macedon

Alexander III 'the Great', 336-323 BC. Drachm (Silver, 20mm, 4.10g 10), possibly Chios or an uncertain mint in Asia Minor, c. 290-270. Head of Herakles wearing lion's skin headdress to right. Rev. ΑΛΕΞΑΝΔΡΟΥ Zeus seated left, to left, triskeles. Price -. Apparently unpublished and unknown. Extremely rare. Very attractively toned and with an especially interesting symbol. Minor marks, otherwise, extremely fine.

Ex Classical Numismatic Group 90, 23 May 2013, 607 and Triton VI, 14 January 2003, 169.
This coin belongs to an interesting group of large flan drachms that are primarily ascribed to uncertain mints in Asia Minor. The style of this piece, however, is so close to coins that can be definitely ascribed to Chios that it is quite possibly from there as well. The triskeles symbol, however, does point to a mint in either Lykia or Pamphylia.
