Note 13 — II COINS OF THE INDO-GREEKS, THE ŚAKAS AND PAHLAVAS

On the Attic standard, adopted by Alexander, the Seleucid and Bactrian kings, the drachm weighed 67·5 grains; on the Persian standard, adopted by the Indo-Greeks (and hence in some works called the Indian standard), it weighed 88 grains, but their coins rarely reach the full weight. Mr. Whitehead, in a recent monograph, “The Pre-Muhammadan Coinage of North-Western India” (Numismatic Notes and Monographs, No. 13, The American Numismatic Society, New York, 1922), calls the two silver denominations of the Indo-Greeks drachms and tetradrachms, thus supposing a separate Indian standard. I have retained the hitherto accepted nomenclature, hemidrachms and didrachms for convenience of reference to standard works.
