As of 1999 three series of coins have been found that confirm Sinuballat was a governor of Samaria. Sinuballat is best known as an adversary of Nehemiah from the Book of Nehemiah where he is said to have sided with Tobiah the Ammonite and Geshem the Arabian. All three coins feature a warship on the front, likely derived from earlier Sidonian coins. The reverse side depicts the Persian King in his kandys robe facing down a lion that is standing on its hind legs.
