Their use ended with Alexander the Great's invasion in 330 BC, after which they were mostly melted down and recoined as coins of Alexander. Close to the end of the 5th century BC, the Persian satraps in Asia Minor decided to strike their own coins. Darius considered such encroachment a crime punishable by death since the right of coinage was treated as an exclusively royal prerogative.

The first Book of Chronicles describes King David as asking an assembly of people to donate for the construction of the Temple. The people gave generously "for...
