The tetradrachm was a large silver coin that originated in Ancient Greece. It was nominally equivalent to four drachmae. Over time the tetradrachm effectively became the standard coin of the Antiquity, spreading well beyond the borders of the Greek World. As a result, tetradrachms were minted in vast quantities by various polities in many weight and fineness standards, though the Athens-derived Attic standard of about 17.2 grams was the most common.

In ancient Greece, the drachma was an ancient currency unit issued by many city-states during a period of ten centuries, from the Archaic period throughout the Classical period, the Hellenistic period up to the Roman period. The ancient drachma originated in the Greece around the 6th century BC. The coin, usually made of silver or sometimes gold had its origins in a bartering system that referred to a drachma as a handful of wooden spits or arrows. The drachma was unique to each city state that minted them, and were sometimes circulated all over the Mediterranean. The coinage of Athens was considered to be the strongest and became the most popular.
