Metal ingots, silver bullion or unmarked bars were probably in use for exchange among many of the civilizations that mastered metallurgy. The weight and purity of bullion would be the key determinant of value. In the Achaemenid Empire in the early 6th century BC, coinage was yet unknown, and barter and to some extent silver bullion was used instead for trade.[2] The practice of using silver bars for currency also seems to have been current in Central Asia from the 6th century BC.[3]
Coins were an evolution of "currency" systems of the Late Bronze Age, where standard-sized ingots, and tokens such as knife money, were used to store and transfer value. In the late Chinese Bronze Age, standardized cast tokens were made, such as those discovered in a tomb near Anyang.[4][5] These were replicas in bronze of earlier Chinese currency, cowrie shells, so they were named Bronze Shell.[6]
