Scanning a maquette to scan gold medals and coins requires special equipment. It records all dimensions of the model, its details, as well as physical aspects of the model. The digital replica serves a variety of reasons during the manufacturing process.
3D Scanning High-resolution scanners can capture physical dimensions and the details of the plaster model. They can also record measurements and geometry through laser scanning and structured light as well as other techniques.
Surface Information Capture - The scanner emits laser or light beams on the model's surface. The scanner tracks any distortions or reflections caused by these laser beams, and therefore can record the surface characteristics of the plaster model.
Data Collection. When the scanner is moving on the plaster it gathers a lot of data points. The result is a digital image of the model's form and contours or other details.
Conversion into 3D Model: The data points are recreated using specially designed software. This model mimics the physical dimensions and features of the maquette.
The Reasons to Create a Digital 3D Model
Digital 3D models allow for precise reproduction of the physical model's details and dimensions. This accuracy will ensure that the final gold coins as well as medals are made to conform to the design intended.
Digital models permit easy modification or improvement. Designers can make adjustments to the 3D model without altering the initial plaster model making it possible to make improvements or corrections over time.
Compatibility with Manufacturing Processes- Digital 3D models are compatible with a variety of manufacturing techniques like 3D printing or CNC machining, facilitating the production of molds or dies for mass production.
Digital 3D models serve as a document for the design. They can be archived digitally to be used in future reference, reproductions, and historic documentation.
Designers and producers can make use of advanced manufacturing techniques to create gold medals and coins which are exact and faithful to the original designs by scanning the plaster models and generating digital 3D models.

How Does A Janvier Transfer The Gold-Colored Design Of A Coin Or Medal That Is On The Master Hub Onto Working Hubs?
A Janvier machine is also known as pantograph, also known as a reducing machine. It is employed to transfer the appearance of a coin medal from the master to an operating center. The Master Hub Creation is explained in this video.
The master hub is the die or mold, that contains the exact design for the coin or medal. It's produced with precision CNC manufacturing.
Janvier Machine - Installation and Setup
The Janvier machine has an instrument to trace the design on the hub master and an aide-memoire cutter that replicates the design.
The Janvier machine is equipped with a master wheel attached to the machine. It is used as a model, from where designs are transferred.
Tracking The Design
The Janvier machine has stylus which is designed to follow the contours, features and the design of the master wheel. As the stylus moves across the surface of the master hub, it tracks the design's shape.
Reduce the DesignReducing the Design
On the Janvier the cutting tool copies the designs traced onto the central hub of the machine that is typically constructed from an abrasive material such as steel or Nickel.
The cutting instruments reduce or duplicate the design at the smaller scale or a reduced size, in comparison to the master hub. This reduction is vital in the process of minting, since it allows the striking of coins or medals in the size you want.
Accuracy and precision
Janvier's machine is operated with precision, ensuring an exact transfer of data from the master hub to the hub for operation. It replicates every detail and contour with accuracy.
Quality Control
The quality of the resulting hub is checked to ensure that the design of the transfer meets the specifications required for the striking processes.
Additional Processing
The Janvier machine makes a functional hub that is used in the coin and medal striking process. It functions as a mold, die or die to make multiple medals or coins blanks that have the transferred design.
Janvier's machine is crucial for coining. It allows accurate replication and reduction from a master to working hubs of complex designs. Working Hubs are utilized to produce large quantities of coins or medals through the process of striking.

How Are Gold Coins And Medals Shielded From Corrosion With A Coating?
The coating process can be utilized to safeguard, improve appearance, or create specific aesthetic effects. Here are the different types of coatings that are used.
Clear Protective Coatings (Varies). A clear protective coating such as lacquer a specialized plastic, can be used to shield the surface from oxidation tarnishing or scratches. This coating protects and preserves the original appearance of the coin or medal.
Improvement of Appearance
Gold plating, or gildingA surface of a gold coin medal can be gilded or coated with a thin layer of gold. This gives a beautiful look to the coin or medal.
Aesthetic Effects
Patina and Antique Finishes Special coatings can be applied to create the antique or patina appearance. This adds depth and character to the design, by creating an aged and oxidized look.
Coloration and Coloring- Certain parts of a coin or medal coins are colored with specific coatings or enamels. This is done to emphasize certain design elements, add interest, or to create an interest in the eye.
Anti-Tarnish Coatings-
Anti-Tarnish Solutions: For coins or medals with intricate designs or surfaces susceptible to tarnish, anti-tarnish coatings or solutions could be used. These coatings stop the metal surface from discoloring or oxidizing over time.
Specialized Coatings to Protect or authentication
UV-Reactive Coatings or Luminescent Coatings Certain coins and medals might have special coatings which react with UV light. This can reveal the hidden or encrypted components to provide security or authentication purposes.
Selective Coatings To Enhance Contrast
Selective Coating Removable- In certain cases the coatings of medals or coins are removed selectively to create contrast between polished and coated surfaces.
Every coating serves a specific purpose. It could be used to protect the metal or enhance its appearance. They can also be used to add security features. These coatings can significantly impact the durability and visual appeal of gold coins and medals. They also enhance their value.
