Denarius

The chief sllver coin among the Romans, worth 8d.; it was the seventh part of a Roman ounce. Also an English penny. The denarius was first coined five years before the first Punic war, B. C. 269. In later times a copper coin was called "denarius." Smith, Diet Antiq.

— Denarius Dei. (Lat "God's penny.") Earnest money; money given as a token of the completion of a bargain. It differs from arrlug in this: that arrhæ is a part of the consideration, while the denarius Dei is no part of it. The latter was given away in charity ; whence the name.

— Denarius tertius comitatfis. In old English law. A third part or penny of the county paid to its earl, the other two parts being reserved to the crown.
