Why Was the Coin Invented?

By GovMint :

Coins were invented to simplify and standardize trade, replacing the cumbersome barter system and the use of metal ingots. The earliest coins are believed to be made by the Lydians around the 7th century BCE from a naturally occuring alloy called electrum. The concept of change quickly spread from Lydia to other regions in the area, including Greece and Persia.

Coins soon became integral to many economic systems, facilitating commerce by providing a standardized medium of exchange that was widely accepted and trusted.
