During the excavations at the Armon Ha-Naziv Tunnel, 61 coins were discovered, 33 of them unidentifiable. All the coins are bronze except for one silver Crusader obole. The coins uncovered within the foundation trench of the tunnel date its construction to the first century BCE, from the days of Alexander Jannaeus to Herod. The remainder of the coins is related to the later periods of use of the aqueduct and adjacent installations, during the Byzantine and Islamic periods.
