Miliaresion

Example of the first miliaresia, struck by Leo III (r. 717–741) to celebrate the coronation of his son, Constantine V (r. 741–775), as co-emperor. Notice the lack of any imagery except the cross.

The miliaresion (Greek: μιλιαρήσιον, from Latin: miliarensis), is a name used for two types of Byzantine silver coins. In its most usual sense, it refers to the themed flat silver coin struck between the 8th and 11th Century.
