Coins were first appeared as a method of payment around the 6th or 5th century BC.

Early Greeks minted coins for the Egyptians. When Lydia was conquered by the Persians in 546 BC, coins were introduced to Persia. The Phoenicians did not mint any coins until the middle of the fifth century BC, which quickly spread to the Carthaginians who minted coins in Sicily. The Romans only started minting coins from 326 BC.

Coins were brought to India through successor kingdoms of Alexander the Great.

In China, gold coins were first standardized during the Qin dynasty (221-207 BC). After the fall of the Qin dynasty, the Han emperors added two other legal tenders: silver coins and "deerskin notes", a predecessor of paper currency which was a Chinese invention.

The average coin collector of the 21st century is likely to be interested mainly in modern or classic coins from the U.S. or other countries that were issued in the past couple hundred years. They often don’t pay very much attention to ancient coins because they think they are too expensive or difficult to collect.

The reality paints a stark contrast. There are many ancient coins in the marketplace today, and many of them are actually very affordable. Moreover, collecting ancient coins today is less challenging than in the past because of all the information available online. You can see other useful resources for collectors discussed in a previous article I authored, Ancient Coins Offer Great Potential.
