Comment
Source: Online Coins of the Roman Empire (OCRE)Interesting fact
The Orichalcum used in the production of this coin was a valuable and highly sought-after metal in ancient times, believed to be a brass-like alloy composed of copper, zinc, and sometimes small amounts of gold or silver. Its name is derived from the Greek words "oros" (mountain) and "chalkos" (copper), likely due to its shiny, golden appearance. The use of Orichalcum in coinage was a significant innovation during the reign of Hadrian, as it was more durable and resistant to corrosion than other metals commonly used in coin production at the time.
