Definizione

• A name given to certain pieces in the Roman series, the use of which has not been satisfactorily determined. They exist in both bronze and lead, and usually have a figure or portrait on one side and a numeral of value on the reverse. It is generally supposed that they were employed as temporary substitutes for money, such as for admission to the ancient games, theatres, etc.
