Greek A gold coin of one misqal weight, or ninety-six barley grains, worth about ten shillings
According to Mr. Hussey (Ancient Weights, p 142), the average weight of the Roman denarii, at the end of the Commonwealth was sixty grains, whilst the English shilling contains eighty grains. Mr. Lane, in his arabic dictionary, says, “its weight is seventy-one barley-corns and a half, nearly, reckoning the daniq as eight grains of wheat and two-fifths; but if it be said that the daniq is eight grains of wheat, then the dinar is sixty-eight grains of wheat and four sevenths. It is the same as the misqual.” The dinar is only mentioned once in the Qur’an, Surah ii 66: “And some of them if thou entrust them with a dinar, he will not give it back.” It frequently occurs in books of law.
