A gold coin or gold medal design can be used as a design reference by the designer or artist. This design may be a simple sketch drawn with a pencil, or it may be a digital image made using graphic software. You can also use other materials like clay or wax.
Preparation of Plaster- Plaster is mixed with water to make an easily workable consistency. It's important to have an even mixture that is free of lumps.
Creating the BaseThe base, also known as a platform is made in which the maquette is created. This base could be a board of wood or a flat surface which provides stability.
The Maquette is sculpted using the gold pattern as a template. This is the process of making the plaster into a 3D or relief representation of the coin.
Refinement and detailThe artist focuses on adding more details, enhancing the contours, and also ensuring the accuracy of features and proportions within the design. This stage demands accuracy and focus.
It is important to allow the plaster to dry out and setWhen a sculpture is done, it will require some time to set and set. This will allow the maquette to harden and retain its shape.
Following drying, the surface is cleaned to remove bumps and rough spots.
Sealing and Preservation - To preserve maquettes, and to prepare them for the future process for scanning, or mold making, an adhesive or protective layer can be applied.
The resultant plaster maquette acts as a tangible representation for the design of the gold coin or medal. The maquette of plaster is used to design molds to make mass-production production possible and also to serve as a source material for other stages of the production process.

The vacuum oven eliminates all air from the room making it a clean space free of oxygen as well as other gases. This guarantees uniform heating, and also prevents the oxidation process from occurring.
Heating Phase
The furnace is heated up to the desired temperature needed to harden the dies. The temperature will depend on the material that is used and how it is to be shaped.
Drinking at high temperatures
Die dies need to be kept at a high temperature for a certain duration to allow the material to achieve the desired hardness.
Quenching (or Cooling)
Using specialized methods that allow dies to be quickly cool down or melted after the soaking process. The fast cooling process ensures the desired toughness and hardness of the steel.
Tempering Optional
In some cases, the hardening is followed by a tempering process. Tempering involves heating the dies to a lower temperature in order to ease stress and maintain their toughness.
Quality Control and Inspection
The hardened molds are thoroughly checked and verified to ensure that the dies are in compliance with all of the specified requirements.
Post-Treatment Handling-
After the process of vacuum hardening is finished Die dies are then subject to further processes like polishing or coating before they are used for the coin or medal striking process.
