What is a greek scruple coin?
A scruple is not a coin, but a weight. And the word is not
Greek, but Latin in origin. The word scruple comes from a Latin
word meaning sharp pebble, and this is true of both the English
word for a weight and the word for a moral consideration.
As a weight, a scruple is in the apothecaries' series of the
English system, and is one third part of a apothecaries' dram. The
word dram comes from the Greek word drachma, which was both a
weight and a denomination of coinage. Perhaps it is from this
connection that the idea came of its being a Greek coin.
