Hemidrachm

The hemidrachm (literally "half-drachm") was a fractional silver denomination struck across the Greek world, typically weighing between 1.5 and 2.5 grams depending on the local weight standard. Hemidrachms served as everyday coinage for smaller transactions where a full drachm or tetradrachm was too large a unit of value. The denomination was produced by numerous mints from the archaic period through the Hellenistic age, with notable series from Corinth, the Achaean League, Bactria, Parthia, and various cities of Asia Minor. The coin's small size limited the detail possible in die engraving, but many hemidrachms still display accomplished artistry, particularly the Pegasus types of Corinth and the royal portrait issues of the Hellenistic kingdoms. Because hemidrachms are smaller and less visually dramatic than tetradrachms, they tend to be more affordable and less widely collected, creating opportunities for specialists. Identification requires attention to weight standards, monograms, and control marks, as many issues are difficult to attribute without specialist references. SNG volumes, regional corpus publications, and specialized monographs are the standard catalog resources. Hemidrachms from the Bactrian and Indo-Greek kingdoms are among the most historically significant, documenting rulers and regions otherwise poorly attested in the literary record.
