The dupondius, formerly a two-pound bronze coin, was now orichalcum, valued at half a sestertius and weighing half as much. The half-ounce as, worth half a dupondius, the semis, worth half an as, and the quadrans, worth half a semis, were the first pure copper coins minted in Rome since 84 BC. [3]
Unlike most modern coins, Roman coins had (at least in the early centuries) significant intrinsic value. However, while the gold and silver issues contained precious metals, the value of a coin could be slightly higher than its precious metal content, so they were not, strictly speaking, equivalent to bullion .
At the time, it was known as the Year of the Consulship of Augustus and Varro (or, less frequently, year 731 Ab urbe condita). The denomination 23 BC for this year has been used since the early medieval period, when the Anno Domini calendar era became the prevalent method in Europe for naming years.

Double-die style struck coin from Ancient India, c 304-232 BCE featuring an elephant on one face and a lion on the other. Since that time, coins have been the most universal embodiment of money. These first coins were made of electrum, a naturally occurring pale yellow mixture of gold and silver that was further alloyed with silver and copper.
The coins weight about 3.9 grammes, which is the normal weight for a denarius coin. Their silver content is 92.2%, the same as the cistophorus (the main coinage in the province of Asia ), but lower than contemporary denarii struck at Rome, which had a silver content of 96.84%.
