The stater (/ˈsteɪtər/ or /stɑːˈtɛər/;Ancient Greek: στατήρ IPA: [statɛ̌ːr], literally "weight") was an ancient coin used in various regions of Greece. The term is also used for similar coins, imitating Greek staters, minted elsewhere in ancient Europe.
The stater, as a Greek silver currency, first as ingots, and later as coins, circulated from the 8th century BC to 50 AD. The earliest known stamped stater (having the mark of some authority in the form of a picture or words) is an electrum turtle coin, struck at Aegina that dates to about 700 BC. It is on display at the Bibliothèque Nationale of Paris. According to Robin Lane Fox, the stater as a weight unit was borrowed by the Euboean stater weighing 16.8 grams from the Phoenician shekel, which had about the same weight as a stater (7.0 grams) and was also a fiftieth part of a mina.
The silver stater minted at Corinth of 8.6 grams weight was divided into three silver drachmas of 2.9 grams, but was often linked to the Athenian silver didrachm (two drachmas) coin weighing 8.6 grams. In comparison, the Athenian silver tetradrachm (four drachmas) was weighing 17.2 grams. Staters were also struck in several Greek city-states such as, Aegina, Aspendos, Delphi, Knossos, Kydonia, many city-states of Ionia, Lampsacus, Megalopolis, Metapontium, Olympia, Phaistos, Poseidonia, Syracuse, Thasos, Thebes and more.
