British Mandate Palestine, that is. You know, the coins with the Hebrew and the Hebrew initials for "Eretz Yisrael."
Remember, the Palestinian Arabs at the time were dead set against a Palestinian currency. When they were issued in 1927 their leaders called to boycott the currency altogether and continue to use the Egyptian pound as they had been.
What kind of nationalist wouldn't want their own currency? But that is not the correct framing of a question. In 1927, the very term Palestine was associated with Jews far more than with Arabs. Only Jews identified as Palestinian.
It is ironic that a currency rejected by Arabs in Palestine in 1927 should be celebrated by their descendants today.
