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. Orichalcum was used in various Roman coins during the 2nd and 3rd centuries AD and was prized for its durability and resistance to corrosion.
