Dirhem Pubblico Deposited
A Muhammadan silver coin, first issued in the latter part of the seventh century. The name is a modification of the Greek Drachma. The weight of the Dirhem originally was forty-six grains, but both the weight and size have undergone many variations.
Originally the Dirhem was one tenth of the Dinar, but this relation was not kept up.
The legal Dirhem is a money of account; the actual Dirhem of currency varied greatly in weight, e.g., in 710 the Egyptian Dirhem weighed 64 Habbehs, at other times 48. The divisions of the Dirhem are into 6 Daniks, or 14 Kirats, or 70 Barley-corns.
