Coining

Author: sreejith

Coining is a type of metalworking which involves precision stamping. The process consists of the work piece being made to undergo a high level of stress which makes the plastic flow inside sufficiently on to the metal’s surface. In certain kinds of metals, the plastic flow system works to lessen the grains sizes on the surface, sometimes, resulting in hardening of the work surface, and the metal inside the work piece remains ductile and tougher. The coining procedure is used basically to create coins, money, badges for the police, and buttons for fire fighters, springs with precision energy, and accurate parts for small sized polished surfaces.

The coining process is an ancient process involving a cold working system, which requires a large amount of strength to re make the work piece plastically. It needs to conform with a die as well. The coining process can be conducted by a gear-driven system or even a mechanical press. Otherwise, a more common system used is the hydraulic press. Coining needs to be done in high levels on tonnage presses, much more than what is needed in the stamping procedure. Coining is basically a manufacturing process that creates various parts for different industries.

A coin is created by striking the sides of the metal coin-like piece with two metallic pieces, one of which is a coin die. The die will have the reverse image that is to be produced on the coin, therefore when it is pressed against the coin; it rights itself into the desired picture. Today’s dies are able to produce many coins before they have to be replaced, since they are made out of hardened steel. The Coining dies are mainly of 3 types – the ancient coining dies, the medieval coining dies and the modern coining dies.

Many treasure-seekers and artefact collector have gone looking for ancient coining dies, as they are invaluable in today’s world.
