Tetradrachms, like this coin, were struck from almost pure silver. They can be said to have been the world’s first truly international coinage as they were recognised throughout the ancient world as a standard unit of value.
They were made from thick blanks and detailed in high relief with Athena, the Greek goddess of wisdom, on the obverse, accompanied by her symbol the owl on the reverse of the coin.
