In a recent gathering, someone was wearing a drachma pendant…

According to Secretary of Pontifical Biblical Commission Vigouroux in his 1895 publication "Dict. de la Bible," the term “drachma” is derived from “daraq-mana,” the name of a Persian coin (Achaemenid Persian Empire 550-330 BCE) equivalent to the Hebrew “drkmwn”… “Daric” was another word for the darag-mana because it was first struck by the Persian emperor Darius the Great.

Univ of Oxford prof H. G. M. Williamson notes in his book “Studies in Persian Period History and Historiography” (2004) that ancient Greek writers knew “dareikos” derived from the name of Persian king Darius.

In “The International Standard Bible Encyclopedia” (1979), Geoffrey W. Bromiley defines “DARIC dar'ik [Heb. darkftnon, 'adarkon; Gk. dareikos]; AV DRAM; NEB also DRACHMA. A Persian gold coin, the first to be mentioned in the Bible.”
