By the end of the fourth century BC the Aegean region had been dominated by coinage using Attic and Rhodian standards. Early Rhodian standard had replaced Aeginetan standard in silver coinage for most Cycladian mints by the third century BC. By Alexander the Great's time Rhodian standard was accepted by most of Ionia, Caria and by numerous states of the Cyclades and Propontis. Alexander's adoption of the Attic weight brought demise of all other weight standards except for the Attic and Rhodian standards.
