How And Why Are Certain Types Of Finishes, Such As The Matte Or Textured Surfaces, Achieved Through Sandblasting?
Sandblasting is a technique used to produce textured or matte surfaces on gold coins and medals. The procedure of Sandblasting is explained.
Surface Preparation - The coin or the medal is placed into a chamber, cabinet or nozzle that is connected to an air compressor. This chamber can be enclosed in order to keep the abrasive substance that is used in the process.
Abrasive material selection - High speed propulsion of fine particles of abrasive materials, such sand or silicon carbide, or glass beads and aluminum oxide on the surface.
High-Pressure-The abrasive grains are propelled onto the surface using compressed air or another high-pressure device. The force and velocity that the particles encounter the surface produce the desired finish or texture.
Texture creation - By altering the surface's topography because of the effect of the abrasive particle it creates a texture. This process can be used to create an even texture or roughen specific regions.
Sandblasting can have its intensity, duration and angle controlled to produce various textures or finishes. Different abrasives and pressure levels produce different results.
Sandblasting - Why it is done
Texture Variation: Sandblasting produces a wide range of textures, such as smooth, frosted and matte surfaces. They can add fascination and unique qualities to medals and coins.
Aesthetic Enhancement: Sandblasting changes the appearance of the surface, reducing light reflections and decreasing shine, which may enhance the coin's or medal's visual appeal. Matte finishes may be used to highlight certain design features by reducing glare.
Anti-Glare Properties - Matte or smooth surfaces created by sandblasting can reduce reflections and glare. This makes the medals or coins visually appealing and easy to see without unwanted light interference.
Contrasting Elements in Design- Sandblasting is employed to create contrasts between areas that are polished or textured on coins or medal. This can be done to highlight specific design elements or increase the dimension and depth.
Sandblasting offers a variety of customization options that allow for artistic expression and allows coins or medals to be designed with different distinct textures or finishes that are unique to the style.
Sandblasting, a method that is versatile that can be used to create various designs and finishes for the surface of coins or medals. It enhances the visual appeal, aesthetics, and overall design.

How Do You Put Blanks Of Gold Into Coin Presses?
In the process of minting gold blanks are loaded into coin presses and then stamped under pressure to turn them into finished coins or medals. Here's a brief overview of how to load blanks.
A feeder system is attached to the coin press. This system loads gold blanks that have been prepared and checked for quality. The feeder system is responsible for ensuring a continuous flow of blanks into the coin press.
Feeding Blanks through the Press
The feeder system guides the blanks one by one into the chamber for striking of the coin press. This ensures the precise positioning of each blank prior to stamping.
Alignment and Positioning
The blanks are placed in the press, and then placed into the striking area making sure that they are perfectly aligned to allow for the stamping.
Striking at High Pressure
The coin press exerts massive pressure on the gold blanks by using two dies: one stationary and one that moves. The stationary die leaves negative marks on the design of the coin while the moving one is the hammer, which hits the blank.
The die that is moving strikes the blank with considerable force, and the design is transferred on the blank surface. The force of the dies creates the design and the relief is raised.
Repetition Striking (Optional)-
For more expensive coins or medals such as collector's or proof editions, multiple strikes could be employed to produce an even more sharp, clear image or style. Each strike fine-tunes the details within the blank.
Collection and Ejection
Once struck, the coins or medals created are taken from the presses. They are then put in containers and trays. The designs that are stamped are examined for quality control to ensure that they meet the standards and standards.
Post-Processing-
In addition to edge letters and refeding, based on the specifications of the design or the mint requirements, some coins or medals will undergo post-strike treatments or other procedures.
Stamping with high pressure, which creates a design onto the gold blanks is critical in that it transforms them into finished coin or medals for circulation, collecting, or commemoration. The process of stamping requires accuracy as any changes in alignment and pressure can impact the final product's quality.
