Claims13
A two-stage embossing method for producing a coin or medal (2), comprising:
- during a first stage of the embossing process, introducing a coin blank (28) into an embossing chamber (22) that comprises an embossing ring (24) and a first and a second embossing stamp (26) facing each other and mounted moving towards each other so that the coin blank (28) is embossed, and
- during a second stage of the embossing process, embossing the respective soundtrack (6) using a die (30) that is inserted in the embossing chamber (22) between the blank (28) and the first and/or second embossing stamp (26).
A galvanic manufacturing process for producing a die (30) for the embossing process of a coin or medal (2), comprising:
- providing a metal plate with a plastic layer into which a soundtrack (6) of the die (30) is introduced by means of a graver,
- subsequently galvanically providing the plastic layer with a layer of silver electrolyte, onto which again a separating agent is applied, and
- subsequently galvanically providing the separating agent with a nickel layer that is used as a die (30) after being removed.
