Coin Making – From Ancient Craft to Vital Technology

Scholars point to Greeks living on the western coast of Turkey in Lydia during the 5th century BCE as the first coin makers. They used a metal called electrum, a naturally occurring alloy of silver and gold. Like modern coins, the first coins were issued by a governing authority.

Coins were stamped with images popularly identified with that authority.

Unlike the coins of today, the first coins had an intrinsic value equal to their nominal value.

The metal the coin was made from was equal in value to its “face value”, that is, the value assigned to the coin by the issuer.

Conceptually, a coin was a more convenient way of transacting business. Its advantage over barter was clear. It was much easier to carry around small pieces of valuable metal than swappable goods.

This was revolutionary. And it required the services of a whole new class of professionals, among whom were mint masters, die sinkers, and coiners. The required skill sets were at once artistic and industrial.

Coins were representative of the nation and the people they served, not to mention the ruler whose image appeared thereon. Coin art was not a casual matter. Coins were designed to reinforce national values, and often the specific agenda of the ruler.

Though the minting methods of the time were rudimentary, the coins of the ancients were often elegant in their execution.

And coins were economically important. They were made to be used, and their success as a medium of exchange meant their efficient production was also important.

As a manufacturing process, minting was anything but efficient, especially in the ancient world. Coins were produced one at a time from hand made blanks and dies, and the use of heavy hammers and anvils.

This method continued throughout the coin-using world until the late 15th century, at which point some mechanization began to seep in.

Improvements in minting methods kept pace with the advancing technology in other sectors of the economy. Muscle power was aided by the application of simple mechanical principles, as in the screw and roller based coin presses. Mechanization grew in complexity, as steam power was introduced.

Coining operations today are conducted in the highly automated industrial facilities that make up a modern mint. Fully invested in the Information Age, these mints produce a stupendous amount of data, along with a prodigious flow of coins.
