Legion Aureus

 is a type of currency in Fallout: New Vegas.

Background
Unlike NCR money, the Legion mints its own currency from silver and gold. Each coin bears the profile of Caesar, with different reverses. The two types are called respectively Legion Denarius (silver) and Legion Aureus (gold).

Characteristics
The Legion Aureus depicts an image of an older Caesar and the phrase 'Aeternit Imperi', meaning eternal rule or authority, on the obverse. The reverse depicts the bull symbol of Caesar's Legion and the phrase 'Pax Per Bellum', meaning peace through war.
