Stamped on one side of the coins are a chalice and Hebrew inscription that translates to "To the Redemption of Zion." On the other side, the coins bear a motif with a bundle of lulav (palm branch) between two etrogs(a type of yellow citron) and the Hebrew inscription "Year Four," referring to the fourth year of the Great Revolt, around the year 69 or 70.
