The city of Tralleis was founded by Aeolians and then conquered by the Persians. Sparta attempted to capture it from the Persians, but it was Alexander the Great who finally succeeded when the city surrendered without a fight. Alexander himself never traveled to the city, but he received a delegation from them while at Miletos and accepted their handover of the city to him.
This coin may have been one of the first coins minted in Tralleis.
