How Is A Plaster Replica Scant To Make An Exact Digital 3d Model Of Gold Medals Or Coins?
Scanning a model made of plaster to create a digital 3D model for gold coins or medals requires specially designed equipment to record the maquette's physical details and dimensions in the digital format. This digital replica serves multiple reasons during the manufacturing process.
3D ScanningHigh-resolution 3D scanners are used to capture the dimensions and specifics of a plaster model. The scanners employ various techniques such as laser scanning and structured light to capture precise dimensions and geometrical shapes.
Capturing Surface Information- The scanner emits light or laser beams on the surface of the plaster model. The scanner captures the distortions and reflections these beams cause, thus capturing surface information.
Data Collection- As it moves along the surface of the plaster models the scanner collects a large number of data points. These data points are later used to build an electronic model of the model that includes its geometry, contours details, and so on.
Conversion into a 3D Model. The collected data is processed by special software that converts it to an electronic 3D model. This model resembles the physical dimensions and characteristics of the maquette.
What are the motivations for creating an electronic 3D model?
Digital 3D models allow for exact reproduction of physical models' details and dimensions. This will ensure that the final gold coins and medals are created to be in line with the original design.
Digital models permit easy adjustment or refinement. Designers can modify the 3D models without altering their initial plaster model.
Compatibility with various manufacturing processes- Digital 3D designs are compatible with various manufacturing techniques like 3D printing and CNC machining which makes it much easier to make molds and dies for mass production.
Digital 3D models are used as a record of the design. They can be archived digitally to be used in future reference as reproductions, historical documentation.
Through scanning and generating a 3D representation of the model in plaster, manufacturers and designers can simplify the manufacturing process, ensure exactness and accuracy when replicating the original model.

How Does A Janvier Transfer The Gold Design Of A Coin Or Medal From The Master Hub To Working Hubs?
A Janvier Machine, also referred to as pantograph machine, or reduction device is a tool used in the coining process to move designs from a Master Hub to a Working Hub. Here's an overview of how it accomplishes this Master Hub Creation-
The master hub, also referred to as the original die or mold, is the first mold or die which contains the exact layout and design of the coin. It is created by CNC cutting, or by using other precision techniques.
Janvier Machine - Installation and Setup
The Janvier machine is made up of a stylus, which trace the design on the hub master and a cutting device that replicates the design onto the hub that is in use.
The Janvier machine is equipped with an incredibly secure master hub. It serves as the template to which the design can be transferred.
Finding the design
The Janvier stylus follows the contours of the design and the details on the master hub. The stylus records the profile of the design when it travels across the surface of the hub.
The Design-
The Janvier machine simultaneously copies the traced-out design onto the work hub. This is usually constructed from softer materials than the master wheel, for example, steel or nickel.
The cutting tool duplicates or reduces the design of the hub in a smaller size or scale in comparison to the hub that is master. This reduction is vital to the process of minting, since it permits the sculpting of medals or coins in the size you want.
Accuracy and precision
Janvier is a high-precision machine that guarantees a precise transfer of design from the master hub onto the hub that is in use. It precisely reproduces every detail and shapes, even the smallest of them.
Quality Control
The final hub is subject to quality checks to ensure it conforms to the specifications for striking and is precise.
More Processing
The Janvier machine's working hub can be used to strike coins or medals. The mold or die is used to create multiple medal or coin blanks using the transferred design.
The Janvier machine plays a crucial part in the production process by allowing the exact replication and reduction of intricate designs on medals and coins from a working hub into a master hub. The hubs that are working can be used for the production process of mass-produced medals or coins.

How Are Gold Medals And Coins Protected From Rust By Coating?
There are a variety of reasons gold coins and medals may be coated. They can be used for the protection of your investment, enhancement to aesthetics or to achieve specific effects. Here are a few different coatings that could be applied.
Clear Protective Coating (Varies)Clear protective coating, such as lacquer or a specially-formulated polymer, may be applied to protect the surface against corrosion, oxidation, or scratches. The coating preserves the coin's or medal's original appearance, and also safeguards the metal underneath.
Enhancement of Appearance
Gold plating, or gilding- The surface of a gold coin medal can be gilded or coated with a thin layer gold. This can enhance the appearance of the medal or coin and gives the appearance of a more polished and a luxurious appearance.
Aesthetic Effects
Patina or antique finishes are produced using chemical treatments or special coats. This process creates character and depth to the design by creating an aged, oxidized look.
Coloring and Colorization- Certain parts of a medal or coin are colored using special coatings or enamels. This is done to highlight certain design elements, create contrast, or create an interest in the eye.
Anti-Tarnish Coatings-
Anti-Tarnish Solutions- For coins or medals with intricate designs or areas susceptible to tarnishing, anti-tarnish coats or solutions might be applied. These coatings are made to keep the metal from discoloring or becoming oxidized in time.
Specialized Coatings For Security Authentication
UV-Reactive Coatings. Certain coins and medals may have coatings that react with UV light and reveal hidden or encrypted components. They are utilized to protect and authenticate the item.
Selective Coatings and Contrast
Removal of selective coatingsIn some instances coatings are removed selectively from particular areas, on the coin or a medal, to create contrast, between polished and covered surfaces, while highlighting the design elements.
Each coating process has an objective whether it's to safeguard the metal, enhance appearance, achieve certain aesthetic effects or security features.

Certificate of Authenticity - The piece could come with a unique certificate of authenticity. The certificate confirms that the coin is authentic. It contains information on the coin's series, the metal content, and the minting.
The reasons why we number coins Differently
Authenticity Assurance- Individual numbering can be a reliable and clear way to confirm that the coin's authenticity in the restricted series. Each number acts like a unique identifier and ensures that a coin is authentic.
Exclusivity and Rarity - Limited issue coins with particular numbers are viewed as being more rare and exclusive. The fact that they are not available in a limited number of coins makes them more desirable and desirable.
Collectible Appeal- Numbered coins provide a unique appeal to collectors that allows collectors to follow and showcase specific numbers within a series. Lower or significant numbers within the sequence may be deemed more important.
Individual Numbering encourages engagement of collectors and their interest in collecting collections or buying specific numbers. Collectors may seek out certain numbers based upon their own preference or other important milestones.
Potential for resales and value- Coins with unique serial numbers can have a higher value on secondary markets, especially in the event that their serial numbers are lower or belong to an extremely sought-after collection. They are coveted by collectors due to their rarity and uniqueness.
Trackability and Documentation - Numbering helps in tracking and documenting each coin's history, aiding in the verification of provenance and authenticity in the collector's market.
Issuers and mints provide an exclusiveness and boost the value of collectible or limited edition coins by identifying them individually.
