The design may be a sketch drawn by hand or a digital image created by using graphic design software. The design may be made in digital form or using graphics design software. It can also be a pencil sketch. It is also possible to use other materials, such as wax or clay.
Plaster preparation is combined with water to create an easily-workable consistency. The mixture must be uniform and free of lumps to create a good mold.
Base Creation- To sculpt the maquette it requires a base or platform must be built. This base could either be a board of wood or a flat surface that provides stability.
Making the Maquette- Using the design of gold as a model, the artist begins sculpting the design into the plaster. This involves shaping plaster into a three-dimensional or relief image of the coin.
Detailing and Refinement - The artist creates details, refines the contours and makes sure that the proportions are accurate and design features. This process demands precision and attention to detail.
Allowing for Drying and SettingWhen the sculpting is complete, the plaster requires time to dry and set. The maquette will harden and hold its shape.
Finishing and Smoothing Finishing and Smoothing - The maquette's surfaces are later polished and refined following drying to remove imperfections bumps, rough areas and bumps.
Preservation and sealingSealing and preservation - A protective coating can be applied on the surface of the maquette to protect it and prepare it for future processes like scanning or molding.
The resultant plaster maquette acts as a tangible representation of the gold coin design or medal. It can be used to represent a number of stages in the production cycle, including scanning to create digital reproductions or making molds to produce large-scale production. Artists may also use it to visualise and refine the design.

Why Do Gold Coin Or Medal Dies Go Through Vacuum Hardening?
Vacuum hardening is a procedure that involves exposing dies to high temperatures and a controlled atmosphere in a furnace. This is the basic information on the dies for vacuum hardening.
To prepare dies that will be used to create coins or medals, they should be clean and free from any contamination or residues.
Loading into vacuum Furnace
The dies are placed inside the vacuum furnace. It is a specially designed heat-treating chamber that can create a vacuum environment.
Evacuation of Air
The vacuum chamber is created by eliminating air from the chamber and creating an environment controlled and completely free of oxygen. This stops oxidation, and also ensures a uniform heat treatment.
Heating Phase
The furnace is heated to the appropriate temperature for hardening of dies. The temperature depends on both the material that is used and the method by which it will be cured.
Soaking at high temperatures
The dies have to be kept at a highest temperature for a specified period of time in order for the material to attain and maintain its desired hardness.
Quenching or Cooling
After the soaking, dies have to be cooled quickly using specialized techniques. Rapid cooling helps to lock the desired strength and hardness within the metal.
Tempering (Optional).
In some situations, a process of tempering can occur as a result of hardening. The dies are heated up to a lower heat to lessen internal stress and increase the toughness of the die, while preserving its hardness.
Quality Control and Inspection-
Dies with hardened material must undergo rigorous quality inspections and control in order to achieve the desired strength, hardness or tolerances.
Post-Treatment Handling-
Dies, once the process of vacuum-hardening is complete, could be further processed, such as polishing and coating, before they are used in the strike of coins or medals process.
The vacuum hardening method increases die durability and wear resistance, and also the life span of the dies used for striking gold or silver coins and medals. The vacuum hardening process is an efficient and reliable method to make dies hard in a controlled, safe environment free of any contaminants.

Colorization / Coloring - In some instances, the color of specific parts of a coin medal, or another item can be achieved through the use of specific coatings and enamels. The aim is to enhance design elements as well as to create contrast and add visual appeal.
Anti-Tarnish Coatings-
Anti-Tarnishing Solutions - These solutions or coatings can be used on coins and medals with intricate designs or are prone to getting tarnished. The coatings are intended to prevent the metal from oxidizing or discoloring in time.
Specialized coatings to protect or authentication
UV-Reactive Coatings or Luminescent Coatings - Some coins and medals could contain special coatings that react with UV light. This exposes secret or encrypted parts, for security or authentication reasons.
Selective Coatings for Contrast
Selective Coating Removal- Sometimes the coating is removed selectively from particular parts of a coin or medal to create contrast between the polished and coated surfaces. This highlights design features.
Each procedure has a particular goal, such as to enhance the appearance or appearance of metal, enhance protection, increase security, or create certain aesthetic results. The coatings be a significant influence on the durability and appeal of gold medals and coins. They also increase the value of their products.
