Round Production
Coin blanks and rounds punching service
At the beginning of every coin and medal stands a blank, also called a round. The later quality of the minting – and thus the medal or coin – depends on the quality of this blank. Round production includes punching, edge upsetting, and polishing. MünzManufaktur operates its own extensive round production facility to ensure both the highest quality and flexibility at all times.
The starting material for round production is what is known as coils – long strips of the material chosen for coins or medals. Our customers can choose between various precious and base metals.
The materials are first fed into a punching machine. A rolling system ensures the material strip moves precisely through the punch. The punching tools are crucial in this process. They are selected or custom-manufactured for each round type. Each tool consists of multiple sharply ground cylinders, matched with corresponding holes through which the blanks are pushed.
After punching the rounds, they proceed to edge upsetting. Here, the edge is formed into a round, cylindrical, or custom shape. Depending on your requirements, the blanks can also be engraved with edge inscriptions.
The shaped blanks are then moved to the final stage of round production: cleaning and polishing. This ensures the best visual finish and prepares the surface optimally for the upcoming minting process.
