The Israeli monetary unit is commonly known as the New Israeli Shekel (NIS). However, there are also some other synonyms for the Israeli currency unit. One of the synonyms for NIS is the Israeli Pound, which was used before the introduction of the shekel in the 1980s. Another synonym for the currency is the sheqel, which is the Hebrew spelling for the word shekel. The shekel is an ancient Hebrew unit of weight, dating back to biblical times, and the modern Israeli currency's name is a nod to this history. Finally, the acronym ILS is also used as a synonym for the New Israeli Shekel.
