Production of fourrées began almost as early as the production of the first coins in the 7th century BC.
The most common method for producing a fourrée was to take a flan of copper, wrap it with silver foil, heat it, and strike it with the dies. If the coin was sufficiently heated and struck hard enough, a layer of eutectic alloy would be produced, fusing the layers together.

The below quote from forumancientcoins.com puts the coin in context:
"In July 32 B.C., Octavian illegally obtained Antony's will and exposed it to the Roman public: it promised substantial legacies to Antony's children by Cleopatra and left instructions for shipping his body to Alexandria for burial. Rome was outraged, and the Senate declared war against Cleopatra (an important distinction, because Octavian did not want the Roman people to consider it a civil war). Octavian's forces decisively defeated the forces of Antony and Cleopatra at the Battle of Actium in Greece in September 31 B.C. In 30 B.C., Octavian chased Antony and Cleopatra to Egypt where they committed suicide. Octavian became master of the Roman world."
