Coin or medal

Abstract

In order to create a long-lasting memento for a musical performance for example, which also has a practical use, a coin or medal is designed with an embossed soundtrack. Furthermore, a method for embossing this coin or medal is proposed.

1 . Coin or medal having at least one circumferential outer edge, wherein the coin or medal ( 2 ) comprises an embossed soundtrack ( 6 ). 
     
     
         2 . The coin or medal as claimed in  claim 1 , wherein the coin or medal ( 2 ) comprises the soundtrack ( 6 ) on at least one side. 
     
     
         3 . The coin or medal as claimed in  claim 1 , wherein the coin or medal ( 2 ) comprises no further motif or relief ( 10 ) on the side with the soundtrack ( 6 ). 
     
     
         4 . The coin or medal as claimed in  claim 1 , wherein the coin or medal ( 2 ) comprises at least one further motif or relief ( 10 ) on the side with the soundtrack ( 6 ). 
     
     
         5 . The coin or medal as claimed in  claim 1 , wherein the soundtrack ( 6 ) extending in a spiral shape has an internal diameter of at least 20 mm. 
     
     
         6 . The coin or medal as claimed in  claim 1 , wherein the coin or medal ( 2 ) comprises at least one embossed relief which extends on at least one side of the coin or medal ( 2 ). 
     
     
         7 . The coin or medal as claimed in  claim 1 , wherein the coin or medal ( 2 ) comprises at least one printed image which extends on at least one side of the coin or medal ( 2 ). 
     
     
         8 . The coin or medal as claimed in  claim 1 , wherein the surface ( 4 ) into which the relief is embossed has a high level of smoothness. 
     
     
         9 . The coin or medal as claimed in  claim 1 , wherein the coin or medal ( 2 ) comprises steel, noble metal, a noble metal alloy or a non-ferrous metal or is silvered or gilded or plated with noble metal. 
     
     
         10 . The coin or medal as claimed in  claim 1 , wherein a central opening ( 8 ) is introduced in the centre of the coin or medal ( 2 ). 
     
     
         11 . The coin or medal as claimed in  claim 1 , wherein the soundtrack ( 6 ) is produced by embossing using a die ( 30 ) produced by analogue technology. 
     
     
         12 . The coin or medal as claimed in any  claim 1 , wherein the soundtrack ( 6 ) is comprises vertical and lateral deflection. 
     
     
         13 . The coin or medal as claimed in  claim 1 , wherein the embossed soundtrack ( 6 ) is of a V-shape. 
     
     
         14 . The coin or medal as claimed in  claim 1 , wherein the width of the embossed soundtrack ( 6 ) corresponds to a known coarse groove of record technology. 
     
     
         15 . The coin or medal as claimed in  claim 1 , wherein the distance between the individual grooves of the soundtrack is less than in the case of a commercially available record. 
     
     
         16 . A method for galvanic production of a die for the embossing process of a coin or medal, that comprising:
 providing a metal plate, and adding a synthetic material layer to the metal plate;   introducing a soundtrack of the die ( 30 ) into the synthetic material layer;   galvanically adding a layer onto the synthetic material layer;   applying a separating agent onto the galvanically added layer;   galvanically adding a nickel layer to the separating agent and   detaching the nickel layer, suitable for use as the embossing die ( 30 ).   
     
     
         17 . Single-stage or multi-stage embossing method for production of a coin or medal, comprising:
 introducing a round coin blank ( 28 ) into an embossing chamber ( 22 ) comprising an embossing ring ( 24 ) and mutually opposing first and second embossing stamps ( 26 ) which are mounted to be able to move towards each other;   in a first stage of the embossing process, embossing the blank at a pressure of more than 200 tons;   in a second stage of the embossing process, embossing a soundtrack and/or motif or relief by positioning at least one die ( 30 ) into the embossing chamber ( 22 ) between the blank ( 28 ) and the first and/or second embossing stamps ( 26 ), and embossing the corresponding soundtrack ( 6 ) and/or the motif or relief ( 10 ) of the at least one die on the side of the coin or medal ( 2 ).   
     
     
         18 . The coin or medal as claimed in  claim 1 , wherein the coin or medal ( 2 ) comprises the soundtrack ( 6 ) on a side which is opposite the embossed relief ( 10 ). 
     
     
         19 . The coin or medal as claimed in  claim 1 , wherein the soundtrack ( 6 ) extending in a spiral shape has an internal diameter of 30 to 50 mm. 
     
     
         20 . The coin or medal as claimed in  claim 1 , wherein the surface ( 4 ) into which the relief is embossed has a roughness of <5 μm.
