Production Method
After two completely separate blanks have been produced, the outer edge of the nickel-brass blank is raised and edge lettering is applied on a rimming machine. This then passes on to a piercing press which punches out the central hole.
Meanwhile, the cupro-nickel blank has also been rimmed and given a special edge groove to provide a key for the outer nickel-brass ring.
Both blanks are then fed individually into a coining press where the cupro-nickel blank is dropped into the centre of the nickel-brass ring.
The upward movement of the bottom die compresses the blanks against the upper die with a force of around 100 tonnes.
