The hemidrachm was an ancient Greek coin that represented half of a drachm, one of the primary denominations of Greek currency. The name “hemidrachm” comes from the Greek words “hemi-” meaning “half” and “drachmē” meaning “a unit of weight” or “coin,” reflecting its value as half of the standard drachm. The hemidrachm was part of the broader system of Greek coinage, which included a variety of fractional coins to facilitate daily commerce in different city-states and regions.
