Benefits of technology

The invention provides a solution for making coins or medals that can be used as a memento for many years and have very few visible changes over time. The coins or medals are made using a special embossing process which ensures high stability and can hold a lot of information. The use of metals also allows for a smaller size of the coin or medal, making it easier to transport. The patent describes a specific embossing method where a V-shaped soundtrack is embedded into the surface of the coin or medal, allowing for stereo recording. The use of a very smooth embossing process and a small gap between the embossing stamp and embossing ring ensures minimal material loss. Commercially available record players can also play the embossed coins or medals.

Problems solved by technology

Chocolate is a highly perishable material which also does not have a high level of temperature stability.

Embodiment Construction

[0039]FIG. 1 shows a top view of a coin or medal 2 in accordance with the invention with a circumferential outer edge 3.

As in the case of a commercially available record, the soundtrack 6 consists of a continuous uninterrupted groove which extends at a small distance from the outer edge of the coin or medal 2 to the free surface in the middle thereof. This free surface in the middle of the coin or medal 2 in which there is no soundtrack 6 is necessary since this region, by reason of the design of a commercially available record player 12, cannot be played and has a diameter of approximately 20 mm to 50 mm in the case of a coin and 50 to 100 mm in the case of a medal. However, if a dedicated playing device for the coin or medal 2 is made, it would be possible to make it in such a way th...
