This superb detailed portrait of Alexander the Great is on a silver Tetradrachm from the mint of Kaunos in Turkey. The iconic head of Alexander, with god like features and wearing the lion's skin headdress, is forceful and arresting. If you want a portrait of the most famous ruler of the ancient world, this would be a very good choice.

The coin will be offered at auction at Spink in London on 25 June. It is currently available for viewing in our London showroom.
