The Hemilitron denomination
The Hemilitron was an ancient Greek denomination in the Sicilian Litra system corresponding to half a Litra - or six onkia. It was struck in both bronze and silver, and is typically characterized by six pellets on the reverse design.
Some Roman republican bronzes are also referred to as hemilitrons - what they were known as historically is unknown.
