First coins

The question of the world's first coin has long been and still is debated. Among numismatists, it is debated whether the world's first coins originated in Lydia, China, or India (where coins were known as karshapana).[3][4] One early coin from Caria, Asia Minor, includes a legend "I am the badge of Phanes," though most of the early Lydian pieces have no writing on them, just symbolic animals. 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 Ephesos, also called the Ephesian Artemision (which would later evolve into one of the Seven Wonders of the ancient world). Many early Lydian coins were undoubtedly struck (manufactured) under the authority of private individuals and are thus more akin to tokens than true coins, though because of their numbers it's evident that some were official state issues, with King Alyattes of Lydia being the most frequently mentioned originator of coinage.

The first Indian coins were minted around the 6th century BC by the Mahajanapadas of the Indo-Gangetic Plain. The coins of this period were punch marked coins called Puranas, Karshapanas or Pana. The Mahajanapadas that minted their own coins included Gandhara[5], Kuntala[6], Kuru[7], Panchala[8], Shakya[9], Surasena[10], and Surashtra[11]. Some argue that Indian coins were developed from Western prototypes, which the Indians came in contact with through Babylonian traders.[12]

The first European coin to use Arabic numerals to date the year minted was the Swiss 1424 St. Gallen silver Plappart.
