Denomination: 20 Nummia, Bronze
Date: 500-900 CE

History:

Nummus (Greek: νουμμίον, noummion) is a Latin term meaning "coin", but used technically for a range of copper coins issued by the Roman and Byzantine empires during Late Antiquity.

This coin was minted in bronze throughout the Byzantine Empire in wide variety. The “K” stands for the coin’s value, which is 20 nummia (equal to half a follis). The word “ANNO” that is written to the left of the “K” means “year” and the Roman numerals to the right of the “K” was the reigning year of the emperor who is depicted on the reverse side of the coin.
