Claims12
A two-stage embossing method for producing a coin or medal, comprising:
- during a first stage of the embossing method, introducing a coin blank into an embossing chamber that comprises an embossing ring and a first and a second embossing stamp facing each other and mounted to move towards each other so that the coin blank is embossed to compact and smooth at least one surface of the coin blank to form a planar, smooth surface, the first stage being performed without inserting a die into the embossing chamber, and
- during a second stage of the embossing method, embossing a soundtrack using a die that is inserted in the embossing chamber between the blank and the first and/or second embossing stamp to emboss the soundtrack into the planar, smooth surface of the coin blank.
