Alexander the Great ruled from 336 to 323 BC, but most of the coins struck in his name were posthumous issue, some (as this one) more than two centuries after his death.
Denomination : Silver tetradrachm. Mint : Mesembria
Date : ca. 150 to 120 BC (although Price mentions the hoard evidence is a little confusing and it could be a little either side of this).
Reference : Price-1029.
Size : 31.0 x 31.8 mm. Weight : 16.60 grams. (A VERY BROAD FLAN).
Grade : XF with the original nearly black hoard patina intact. The patina is attractive and in my opinion should not be cleaned. There is a very slight double strike on the obverse.
Obverse : Head of Herakles right, wearing the lion's skin.
Reverse : Zeus seated left, holding a sceptre and eagle, with BASILEWS to the right and ALEXANDROU to the left, with LA below the throne and a Corinthian helmet by Zeus' knee.
