In the Coining Press Room, fork-lift trucks tip crates of blanks into hoppers positioned at the top of the coining presses. From the hopper the blanks are fed into the coining press, each one being inserted into a slot in the dial plate. Spinning around, the dial plate brings each blank in turn to rest on top of the lower die. The lower die moves upwards, pushing the blank into a restraining collar and against the upper die with a pressure of around 60 tons. In this way the blank receives the impression of both dies, while at the same time it is forced outwards to take the design of the collar – plain or milled depending on the denomination. The upper die then moves downwards, pushing the struck coin out of the collar and back down into the dial plate which then moves along and ejects the coin. A modern coining press can strike coins at speeds of up to 850 a minute.
The coins are then packed and stored, ready for despatch.
