This Greek Silver Tetradrachm, weighing at 16.3 grams and measuring 25mm, features an image of Athena and an owl and is estimated to have been minted around 400 BC. It has been cleaned and is composed of silver. The coin has an interesting ownership history, with provenance available. The grade, certification, and era are unspecified. This is a great addition to any ancient coin collection, especially for those who appreciate Greek history. A very heavy piece 16.3 g and 25 mm with the reverse in much better condition than the Obverse. A nice clear owl, but Athena side was a bit more corroded , both sides could still use a light cleaning there is still some soil embedded  slightly on both sides.
