Dupondius
The Dupondius was a Roman coin worth two aces. In the early Republic, he had a weight of two Roman pound ( 655 grams ), but was over time handy and shrank in the Late Republic for their future weighing less than 17 grams.
Marcus Antonius provided the first coin with a value character by letting hit on the back of a B. How could they better differ from the similarly-sized aces.
In the early imperial period the coin material was chosen as a distinguishing feature. While Quadrans and As were beaten in a strong copper-containing bronze versions of Dupondien and sesterces were held in brass.
Since the Flavians ( 69-89 AD) were again provided the coins with stamps. The double piece of Ace wearing from now on the radiate crown on the head of the ruler, or a crescent moon, if it was a female portrait.
Beginning of the 3rd century, the minting of Dupondien due to high inflation has been set.
