- History of coins
The history of coins extends from ancient times to the present, and is related to
economic history , the history of minting technologies, the history shown by the images on coins, and the history ofcoin collecting .Coins are still widely used for monetary and other purposes.All western histories of coins begin with their invention at some time slightly before or after 600 BC in
Lydia . Since that time, coins have been the most universal embodiment ofmoney . These first coins were made ofelectrum , a naturally occurring pale yellow mixture of gold and silver that was further alloyed with silver and copper.Also, the
Persia n coins were very famous in the Persian andSassanids era. There are lots of coins that have been found inSusa and inCtesiphon .The most famous and widely collected coins of antiquity are Roman coins and
Greek coins .The
Byzantine Empire minted many coins ("seeByzantine currency "), including very thin gold coins bearing the image of theChristian cross and variousByzantine emperors .A tomb of the
Shang Dynasty dating back to the11th century BC shows what may be the first cast copper money.Some of the earlyest coins were beaten at the edges to imitate the shape of a cow, in indication of their value. Most coins are circular but some were rectangular.
Minting technologies
Coins were first made of scraps of metal.Ancient coins were produced through a process of hitting a hammer positioned over an
anvil . The Chinese produced primarilycast coinage . Relatively few non-Chinese cast coins were produced by governments, however it was a common practice amongstcounterfeit ers. Since the early 1700s, presses have been used, beginning with screw presses and progressing in the 1800s towards steam driven presses. Recently modern minting techniques involving electric and hydraulic presses have been more commonly employed.ee also
