EL Coinage
Electrum is a naturally occurring alloy of gold and silver, with trace amounts of copper and other metals. It naturally occurs in in western Anatolia, and it is here that the first coins were made.

Many early Lydian coins were minted by merchants as tokens to be used in trade transactions, and the Lydian state also minted electrum coins, most of the coins mentioning king Alyattes of Lydia, who is often credited with the invention of coinage.
