DIDRACH'MA and DIDRACH'MUM (δίδραχμον). A double drachm, of the Greek silver coinage. (Tertull. Praescr. 11.) Like the drachma, it was of two different standards: the Attic, of which specimens are very rare, worth about 1s 7½d of our money; and the Aeginetan, worth about 2s 3½d, the largest coin of that standard, and by no means uncommon; one of which (Didrachma/1.1) is here represented of the actual size, from an original in the British Museum.
