Artists employ various techniques to create sketches and designs for gold coins or medals, adapting traditional methods or utilizing digital tools for visualizationHand-Drawn Sketches
Sketches using pencils and pens Artists begin by sketching on paper using pencils and pens. These sketchy sketches help you to visualize the design and layout of the coin or medal.
Detailed rendering- The artist refines sketches adding details, contours, and also fine-tuning the overall composition. This process may require several variations to get the desired effect.
Inking or Tracing. Once the artist is happy with the pencil sketch, they will ink the outline of his final sketch for a cleaner appearance. It is common to trace the pencil sketch on paper that is fresh or use a tracing paper for this step.
The use of shading and depth techniques may be employed to enhance the look of a medal or coin, enhancing its realism. They can also emphasize particular elements.
Digital Design Creation
Graphic Design Software - Artists who are proficient in digital design utilize software such as Adobe Illustrator, Photoshop or specially designed programs for 3D modeling. They design the coin or medal digitally using tools for precision and scale.
Vector Graphics- Digital design is often made using vector graphics. The ability to scale can be achieved without compromising quality. This lets the design be resized for different coin sizes without compromising its clarity.
3D Modeling: Professional artists can utilize 3D modeling software to show the designs of medals and coins in a 3-D environment. This will allow for an authentic representation, as well as a greater understanding of what the finished product is going to look like.
Visualization: Artists are able to render their digital designs in order to create a simulation of the way a medal or coin will appear like when it is finished. They can apply a variety of finishes, effects, or textures.
Digital designs or hand-drawn drawings require a superior level of artistic skill and an understanding of the technical specifications and limitations for the production of coins and medals. Artists may choose their preferred method based on personal expertise, client requirements or the aesthetics desired of the final product.

What Does An Janvier Machine Transfer The Design Of The Gold Coin Onto The Hub That Is In Operation?
The Janvier machine (also known as pantographs, or reducers) is a special device that transfers an image of a coin or medal from the master hub onto the operational hub. The Master Hub Creation is explained in this video.
The master hub is the first die or mold that carries the exact design of the medal or coin. It is usually made using CNC machine or other precise methods to ensure precision.
Configuration for Janvier MachineSetup for Janvier Machine
The Janvier Machine is comprised of two parts that include a stylus for drawing the design and a cutting tool which cuts the design.
The Janvier machine is fitted with a master hub that serves as a template for the transfer of design.
The Design-
The Janvier machine has stylus which is able to follow the contours, details and shape of the master wheel. When the stylus is moved on the surface of the master hub it tracks its contours.
Reducing the Design-
In tandem with the Janvier the cutting tool replicates the traced designs onto the central hub of the machine that is typically constructed from a soft material like steel or nickel.
The cutting tool is used to reduce or reproduces the design on the working hub on an enlarge or decreased size when compared to the master hub. This reduction is vital to the process of minting because it allows the making of medals or coins in the desired size.
Accuracy and precision
Janvier’s machine works with precision and guarantees a flawless transfer of design information from the master to the hub. It faithfully reproduces even the tiny details and contours.
Quality Control
The design and quality of the hub is checked to ensure the transfer design meets the requirements for striking processes.
More Processing
The Janvier machine's working hub can be used to strike coins or medals. It is used as a mold or die to create multiple coin or medal blanks that have the design transferred.
The Janvier machine plays an important part in the production process by allowing the exact replication and resizing of intricate designs on medals or coins from a working hub to the master hub. These hubs are utilized to create large amounts of medals and coins with the strike method.

How And Why Is It Possible To Achieve Certain Textures Or Finishes Such As Matte Or Textured Surfaces?
Sandblasting is a process that is used to create specific finishes or textures like matte or textured surfaces, on gold coins or medals. How and why do we use this method?
Surface Preparation - The coin or the medal is placed in a cabinet, chamber or nozzle that is connected to an air compressor. Abrasive materials are usually located inside this chamber.
Abrasive Materials Selection- At high speeds, tiny particles of abrasive substances such as silicon carbide (sand), glass beads or aluminum oxide are propelled onto the surface of the coin or medal.
High-Pressure Propulsion: The abrasive particles are driven onto the surface by compressed air or a different high-pressure system. The texture of the surface is created by the force and speed of the particles.
Texture Creation - The impact of the abrasive particles onto the surface results in a textured or matte appearance, by changing the topography of the surface. This method is used to create a specific roughness in certain areas or create an even texture on the entire surface.
Sandblasting that is controlled- Sandblasting can be controlled for intensity the duration, angle, and intensity of application to produce different textures or finishes. Different pressure levels, abrasives and abrasives can produce different results.
Sandblasting - Why it is done
Texture Variation - Sandblasting creates an array of textures, such as the grainy, matte and frosted surfaces. They can add interest as well as unique characteristics to the medals or coins.
Aesthetic Enhancement - Sandblasting changes the look of the surface, reducing the shine while also diffusing light reflection. This improves the appearance of the coin or medal. Matte finishes help to emphasize certain design features by reducing the glare.
Anti-Glare: A matte or textured finish that is created through sandblasting can reduce reflections and glare. This makes the coins or medals appear more appealing, and they are much easier to read, without unwanted light interference.
Contrasting design elementsSandblasting can produce contrast between the polished and textured parts of a medal or coin. This helps to emphasize particular features or to add visual depth.
Sandblasting can be personalized to create unique designs or textures.
Sandblasting produces different finishes and textures on the surface of gold medals and coins. This improves the overall appeal, appearance, as well as aesthetics.

How Do You Get Gold Blanks Into Coin Presses?
In the process of minting, gold-plated blanks need to be loaded into coin presses, and stamping at high pressure so that they can create finished awards or coins. This is a brief overview of the process involved Loading Blanks-
The gold blanks are placed in the feeder system which is connected to the coin presses. This feeder system assures an ongoing flow of blanks.
Feeding Blanks Through the Press
The feeder system guides each blank to the strike area of the coin presses. This guarantees the exact placement of each blank for stamping.
Alignment and Positioning-
When using the press, blanks should be placed precisely in the strike area to allow the stamping process to take place.
Striking Under Pressure
The coin presses exert high pressure on the gold blanks by using two dies - one stationary and the other mobile. The stationary die leaves negative marks on the design of the coin while it is moving that die acts as the hammer, which hits the blank.
The die is moved and struck the blanks with great force. This transfers the design to the surface of the blank. Die pressure causes relief raised and details on the coin.
Repeated Striking (Optional)Repeated Striking (Optional)
To create a clearer image or to create a more precise style, multiple strikes are sometimes applied to better quality medals and coins, particularly proof editions. Each strike increases the fine details on the surface of the blank.
Ejection and Collection
After they are struck after which the medals and coins are then thrown into trays. The stamped designs are inspected to determine if they conform to the standards set by the manufacturer.
Post-Processing-
In addition to edge lettering and reeding depending on the specifications of the design or the mint requirements, some coins or medals may undergo post-strike or other treatments.
The stamping process under high pressure is vital because it imparts the desired design onto the gold blanks, turning them into finished coins or medals ready for use in collection, circulation, or even commemoration. This process requires precision because any deviation in alignment or pressure can impact the appearance and quality of the final item.
