In the production of coins, a strong pressure of 35 to 200 tons is required for the upper die to transfer the design elements onto the planchet. The pressure required varies according to the denomination of the coin, the alloy used for production, and whether it is intended for circulation or testing purposes. Prior to production, a series of single-stroke tapping is performed to decide which tonnage will be used for the production cycle and to obtain the maximum yield from the dies. This single shot is known as a “die adjustment strike”.
