Celtic coinage was minted by the
Celts from the late 4th century BC to the late 1st century BC. Celtic coins were influenced by trade with and the supply of mercenaries to the Greeks, and initially copied Greek designs, especially Macedonian coins from the time of
Philip II of Macedon and his son,
Alexander the Great. Thus Greek motifs and even letters can be found on various Celtic coins, especially those of southern France.
