The Classical period then began, and lasted until the conquests of Alexander the Great in about 330 BC, which began the Hellenistic period, extending until the Roman absorption of the Greek world in the 1st century BC.The Greek cities continued to produce their own coins for several more centuries under Roman rule.The tyrants of Syracuse were fabulously rich, and part of their public relations policy was to fund quadrigas for the Olympic chariot race, a very expensive undertaking.
The wealthy cities of Sicily produced some especially fine coins.
The coins produced during this period are called Roman provincial coins or Greek Imperial Coins.
The three most important standards of the ancient Greek monetary system were the Attic standard, based on the Athenian drachma of 4.3 grams of silver and the Corinthian standard based on the stater of 8.6 grams of silver, that was subdivided into three silver drachmas of 2.9 grams, and the Aeginetan stater or didrachm of 12.2 grams, based on a drachma of 6.1 grams.), and six spits made a "handful".
The Hellenistic period was characterized by the spread of Greek culture across a large part of the known world.
Greek-speaking kingdoms were established in Egypt and Syria, and for a time also in Iran and as far east as what is now Afghanistan and northwestern India.
