The master hub, sometimes referred to as the original die or mould it is the mold or die that has the exact design and layout of the coin. It's made with precision CNC cutting.
Janvier Machine Installation
The Janvier machine consists of a stylus that traces the pattern on the hub master, and a cutting tool that replicates the design onto the hub in operation.
The Janvier machine's master hub, which serves as a template to which the design will be copied, is positioned with utmost security to the machine.
Tracing Design-
The Janvier stylus in the machine captures the shape of the design while it travels along the surface of the master hub. As the stylus moves over the surface, it record the design profile.
Reduced Design-
The Janvier machine simultaneously copies the traced-out design onto the hub for work. This is usually made from softer materials as opposed to the master wheel like steel or nickel.
The cutting tool cuts or reproduces the design on the working hub at the smaller or smaller dimensions compared to the hub that is used as the master hub. This is essential for the process of minting, since it allows for the striking of coins or medals at the size you want.
Accuracy and Precision
Janvier is a high-precision machine that assures a perfect transfer of designs from the master hub to the hub that is in use. It reproduces with precision all the details and contours, even the smallest details.
Quality Control
The design and quality of the hub is checked to ensure that the design of the transfer meets the specifications needed for striking processes.
Further Processing
The Janvier's hub is a useful instrument for the making of medals and coins. It is used to make several blanks of the medal or coin with the design transferred.
Janvier's machine is crucial for coining. It allows for the accurate replication and reduction from a master hub to working hubs of intricate designs. These working centers are then used to produce large quantities of coins and medals through the strike method.

What Coating Techniques Are Employed To Safeguard Gold Coins And Medals?
Gold medals or coins can undergo coating procedures for a variety of reasons, such as protection, enhancement of appearance or to produce particular aesthetic results. Below are various coating processes used Protective Coatings-
Clear Protective coating (Varies) - A clear protective layer, like a lacquer or polymer, is applied to shield the surface of the medal or coin from tarnishing or oxidation. The coating keeps the original appearance of the coin or medal and shields the base metal.
Enhancement of Appearance
Gold plating or Gilding - A thin layer of gold can be applied to gold medals or coins. This improves the coin's or medal's appearance, giving the appearance of a more polished and a luxurious appearance.
Aesthetic Effects
Patina or Antique Finishes - Specialized coatings or chemical treatments can be used to create an antique finish. The process is designed to artificially age the surface, creating an oxidized or aged appearance which adds personality and depth to the design.
Colorization or coloring- Specific areas of a medal could be colored with special enamels or coatings in order to draw attention to the design elements, add contrast or create visual interest.
Anti-Tarnish Coatings-
Anti-Tarnishing Solutions - These products or coatings are able to be applied on medals and coins with intricate designs, or have a tendency to tarnishing. These coatings prevent oxidation or discoloration of the surface of the metal over time.
Specialized Coatings to Ensure Security or Authentication
UV-Reactive Coatings or Luminescent Coatings Certain coins and medals might contain special coatings that respond to UV sunlight. This exposes the hidden or encrypted components, for security or authentication reasons.
Selective Coatings To Enhance Contrast
Selective Coating RemovedIn some instances the coatings on coins or medals are removed in a selective manner to create contrast when polished and coated surfaces.
Each method serves a specific goal, whether it's to shield metals, enhance appearance, produce specific aesthetic effects, and/or add security. These coatings have a significant impact on the look and durability of gold coins and medals, increasing their value.

How Do You Get Blanks Of Gold Into Coin Presses?
In the process of coining, blanks of gold are loaded into coin presses under high pressure and then stamped to create finished coins or medals. This is a brief overview of the steps involved in loading blanks.
A feeder system is connected to the coin press. This system loads gold blanks that are prepared and tested for quality. This feeder system ensures an ongoing supply of blanks for the machine.
Feeding Blanks into the Press-
The feeder system is able to guide the blanks one by one into the chamber for striking of the coin press. This allows for precise positioning of the blanks.
Alignment, Positioning and Positioning
In the press, the blanks need to be perfectly placed within the area of striking, so that the stamping can be completed.
Strumping in High Pressure
Coin presses put immense pressure on gold blanks with two dies, one stationary and one mobile. The stationary die is equipped with negative designs engraved on the coin, while the moving die strikes the blank.
The moving die hits the blank with great force, and the design is transferred onto the blank's surface. The dies' pressure imprints the designs, creating the reliefs raised and the details of the coin or medal.
Repeated Striking -
To create a clearer image or more defined style, multiple strikes are often used on higher-quality medals and coins, particularly proof editions. Each strike fine-tunes the details inside the blank.
Ejection and Collection
After being struck, newly-minted medals or coins are ejected out of the press into containers or trays. Quality control is performed to ensure the designs adhere to the specifications.
Post-Processing-
If the mint has specified it, they may also apply additional processes, such as edge lettering, reeding the edge, or post-strike treatment.
Stamping gold blanks with the highest pressure is crucial since it imprints the design you want to see on the blanks, transforming them into completed coins and medals which can be used for celebration, collection or circulation. This process demands precision, as any variation in alignment or pressure can affect the quality and appearance of the final item.
