Coins Around The World

The oldest coins are considered by other numismatists to be the Aegina Chelone coins which were minted ca. 700-550 BC, either by the local Aegina people or by Pheidon king of Argos (who first set the standards of weights and measures). In the Bibliothèque Nationale, Paris, there is a unique electrum stater of Aegina. The date of this coin can hardly be much later than about B.C. 700.
The Ancient Greeks spread the Anatolia practice (or vice versa) and extended it to commerce and trade. Coinage followed Greek colonization and influence first around the Mediterranean and soon after to North Africa (including Egypt), Syria, Persia, and the Balkans.
The first Lydian coins were made of electrum, a naturally occurring alloy of silver and gold that was further alloyed with added silver and copper. Many early Lydian and Greek coins were undoubtedly minted under the authority of private individuals and are thus more akin to tokens or badges than true coins, though because of their numbers it's evident that some were official state issues, with King Alyattes of Lydia being a frequently mentioned originator of coinage.
Most of the early Lydian coins include no writing, called a "legend" or "inscription", only an image of a symbolic animal. Therefore the dating of these coins relies primarily on archeological evidence, with the most commonly cited evidence coming from excavations at the Temple of Artemis at Ephesus, also called the Ephesian Artemision (which would later evolve into one of the Seven Wonders of the Ancient World). The fact that the oldest lion head coins were discovered in that temple, and the fact that they were not used in commerce, strengths the scenario that these coins found there may have actually been badges or medals that were issued by the priests of the temple of Artemis, and the name of the person who received the badge or medal was inscribed on it. Artemis in Anatolia was named Potnia Theron, which is translated as "mistress of the animals", and her symbol was the lion and the tiger.
