DRACHMA, an ancient Greek silver coin, in value about 9½d., or equivalent to the French franc. The weight of the Attic drachma was about 66 grains; and the Eginetan was 1/3 of the Attic. An Alexandrian drachma weighing 126 grains has also been found. The weight called drachm, used by the modern apothecary, is equivalent to the eighth part of an ounce, or 60 grains, or 3 scruples.
