What Is The Reason That Dies Used To Strike Gold Coins Or Medals Undergo The Process Of Hardening By Vacuum?
To harden dies for gold coinage or medals, they are exposed to controlled temperatures in an oven that is a vacuum. Here's an overview of the vacuum hardening procedure used for die preparation and Cleaning-
The dies used for striking medals or coins are created by ensuring they are clean and free from any contaminants or residues.
Loading into Vacuum Furnace-
Die dies are then put inside a specific heat-treating room which can generate an atmosphere of vacuum.
Evacuation from Air-
The vacuum chamber is created by eliminating air from the chamber and creating an atmosphere that is free of oxygen. This helps prevent oxidation and guarantees the same heating.
Heating Phase
The furnace is then heated to the temperature desired for the hardening of dies. The temperature range is based on the specific material used and the method of hardening.
Soaking in High Temperatures
Die dies need to be kept at a high temperature for a specific duration to allow the material to achieve and maintain its desired level of hardness.
Quenching or Cooling
Utilizing specialized techniques that allow dies to be quickly cooling down or being quenched following the soak process. The rapid cooling process can help lock in the desired hardness and strength in the steel.
Tempering is an option
In some instances, a tempering process follows the process of hardening. Die dies are heated to a lower heat to ease internal stress and increase toughness, while maintaining hardness.
Quality Control and Inspection-
The dies that are hardened undergo rigorous quality checks and inspections to make sure that they meet the required hardness, strength, and tolerances for dimensionality.
Post-Treatment Handling-
After the hardening process dies can be polished or coated prior to when they are used in the coin or metal strike process.
The process of forming a vacuum enhances the durability and wear resistance and life expectancy of the dies that are used to create medals or coins. The process of hardening by vacuum is a reliable and predictable method to ensure that dies are hardened in a controlled, safe environment free of contaminants.

In What Ways Can Gold Coins Or Medals Undergo Coating Procedures To Shield The Metal?
Coating gold medals or coins is used to serve a variety of purposes. It can be used to protect, improving the appearance or achieving a specific aesthetic appearance. Here are some examples of different coatings that could be applied.
Clear Protective Coatings (Varies). A clear protective coat such as lacquer an specialized plastic, may be used to shield the surface from oxidation scratches, or tarnishing. This coating shields the metal that is beneath the coin or medal and helps to preserve its original appearance.
Improvement in appearance
Gold plating and Gilding Gold medals or coins may be coated with a fine gold layer. This adds a luxurious appearance to the piece or medal.
Aesthetic Effects
Patinas and antique finishes can be created by using chemical treatments, or coatings. This process artificially age the surface to create an aged, oxidized appearance.
Colorization and Coloring- Certain areas of a medal or coin are colored by using specific coatings or enamels. This can be done to highlight specific features of the design, to add contrast, or create visually appealing designs.
Anti-Tarnish Coatings-
Anti-Tarnish Solutions: For coins or medals with intricate designs or surfaces susceptible to tarnishing, anti-tarnish coatings or solutions might be applied. The coatings can stop the metal surface from discoloring or oxidized over time.
Specialized Coatings For Security Or Authentication
UV-Reactive Coatings or Luminescent Coatings Certain coins and medals might have special coatings which react to UV sunlight. This can reveal secret or encrypted parts to provide security or authentication reasons.
Selective Coatings to Block Contrast
Removal of Selective CoatingsIn certain instances, coatings are removed in a selective manner, from certain areas of the medal or coin to create contrast between polished and covered surfaces, highlighting design elements.
Each coating procedure is created to serve a specific goal. This might be to improve aesthetic or security features or even to safeguard the metal. These coatings can significantly improve the look and long-term durability of medals and coins created of gold, thereby increasing their value and appeal for collectors.
