• The
Achaean standard consisted of a stater of around 8 g, divided into three drachms of 2.6 g and obols of 0.4 g; these weights declined over time. It was first used in the mid-sixth century by the Greek city-states of
Sybaris,
Metapontum, and
Croton, which had been founded in Magna Graecia by
Achaeans from the Peloponnese, and it remained one of the main standards in Magna Graecia until the end of coinage following the Roman conquest in the early third century BC. • The
Aeginetan standard, based on the coinage issued by
Aegina had a stater of 12.4 g, which was divided into a half-stater or drachma of 6.2 g, a quarter-stater of 3.1 g, and twelve
obols of 1.0 g each. This was the main trading standard in the Greek world in the
Late Archaic period. In the second half of the sixth century BC, the Aeginetan standard was dominant in the Greek world. It was overshadowed by the Attic standard in the fifth century BC, but continued to be widely used, especially in the
Peloponnese, until around 200 BC, when the
Reduced Aeginetan or
Symmachikon ("Allied") standard was adopted by the
Achaean League. • The
Attic standard was the standard issued by
Athens from the late sixth century BC onwards. It was based on a drachma of 4.3 g, but in practice the main coin was the tetradrachm of 17.2 g. Each drachma was divided into six obols of 0.72 g. It was interchangeable with the
Euboean standard, used by the cities of
Euboea and their many colonies throughout the Mediterranean, which was based on a stater of 17.2 g divided into six hectae of 2.86 g and the two are often referred to together as the
Attic-Euboean standard.
Corinth also used a variant based on a stater of 8.68 g (half an Attic tetradrachm), divided into three units of 2.89 g. In the Classical period, this standard was issued in vast quantities by the
Athenian Empire and became the dominant weight standard used for payment of soldiers and for long-distance trade. The use of the standard by the Euboean and Corinthian colonies meant that it also became the dominant standard used in
Sicily and northwestern Greece.
Philip II of Macedon used the standard for his gold coinage and
Alexander the Great used it for silver as well from 333 BC. It remained dominant in the Eastern Mediterranean in the
Hellenistic period, when it was issued by
Antigonid Macedon, the
Seleucid Empire, and many individual city-states. By the Hellenistic period, the Attic standard had dropped to a tetradrachm of 16.8 g and a drachm 4.2 g. In Hellenistic Sicily and Italy, the Attic standard was retained for gold, but silver coinage was reduced repeatedly until it was replaced by the
Roman denarius around 211 BC. • The
Chian standard was first issued in
Chios in the fifth century. The standard was based on an ideal stater of 15.6 g, but only half-staters (7.8 g) and sixths (2.6 g) were actually issued until the late fifth century. In the fourth century BC, the standard was adopted by
Rhodes and became widespread in
Caria,
Ionia, the states of the
Propontis and the
Cyclades. At the beginning of the Hellenistic period, it was abandoned by Chios in favour of the Attic standard and Rhodes in favour of the Rhodian standard. • The
Cistophoric standard was introduced by the
Attalid dynasty of
Pergamon around 190 BC and remained in use in western Asia Minor until the third century AD. The cistophorus itself was a tetradrachm of 12.6 g, divided into two didrachms of 6.3 g and four drachms of 3.15 g. • The
Milesian standard of the city of
Miletus was based on a stater of 14.2 g, which could be divided into six hectae of 2.4 g or four drachmae of 3.55 g. • The
Parian-Thasian standard was used by the island of
Paros in the Cyclades and its colony
Thasos in the northern Aegean. It was based on a stater of around 10 g and may have originally been a reduced version of the Aeginetan standard. Under the commercial influence of Thasos, the standard was widely used in the fifth century BC by the
Thracian tribal coinages. • The
Persian standard was based on the silver coins minted by the
Achaemenid Empire in Asia Minor, which consisted of a
siglos or
shekel of 5.5 g and a double siglos of around 11 g. Some Greek cities in Asia Minor with close connections to the Persian sphere, such as
Colophon,
Phaselis, and the cities of the
Hellespont, minted drachms and didrachms on this standard in the Classical period. In the third century BC it was used by
Byzantium. • The
Phocaean standard originated in
Phocaea, and was used only for
electrum coinage, which was common in north-western Asia Minor in the Classical Period. It consisted of a stater of 16.1 g, divided into six hectae of 2.68 g. • The
Phocaean/Campanian standard was used by
Velia (a Phocaean colony) and
Poseidonia in southern
Campania in the Archaic and Classical periods and spread from there to the Campanian mints. It had a stater of 7.5 g, divided into two drachmas of 3.75 g. • The
Phoenician standard, used by the city-states of
Phoenicia in the fourth century BC and by the
Carthaginians for some issues, had a shekel of 7.25 g. The standard was adopted by the
Chalcidian League and then by Philip II of Macedon in the fourth century BC, with a tetradrachm of 14.5 g, but abandoned in favour of the Attic standard under Alexander the Great. In Phoenicia and
Coele-Syria, it remained in use in the Hellenistic period in both the Ptolemaic and Seleucid spheres, but with a reduced shekel of 7.1 g (equivalent to a Ptolemaic didrachm). • The
Ptolemaic standard was used by the
Ptolemaic Kingdom for its silver coinage from 294 BC. It was based on a tetradrachm of 14.26 g and a drachma of 3.55 g. It was equivalent to the reduced Phoenician standard used in Ptolemaic Coele-Syria and Seleucid Phoenicia. • The
Rhodian standard, a reduced version of the Chian standard, was introduced by Rhodes around 300 BC and subsequently adopted throughout the Rhodian sphere in Caria and the central Aegean. It consisted of a tetradrachm of 13.4 g, didrachm of 6.7 g, and drachm of 3.4 g. • The
Samian standard was used by
Samos in the fifth century until replaced by the Attic standard in 412 BC. It used a tetradrachm of 13.1 g, a drachma of 3.3 g, and obols of 0.55 g. ==See also==
