How And Why Is It Possible To Achieve Certain Textures Or Finishes, Like Matt Or Textured Surfaces?
Sandblasting is a technique used to produce textured or matte surfaces on gold medals and coins. This is the reason and how it's usedProcess for Sandblasting
Surface preparation- The coin or medal is placed inside an enclosure or chamber with a nozzle attached to an air compressor. The chamber is able to be sealed to keep the abrasive substance that is used in the process.
The medal or coin is then coated with abrasive substance, which can comprise glass beads, sand silicon carbide, or aluminum oxide.
High-Pressure Propeller: The abrasive particle is launched onto surfaces by compressed air. The force and velocity that the particles encounter the surface create the desired finish or texture.
Texture Creation- The impact of the abrasive particles on the surface creates a textured or matte appearance by changing the topography of the surface. This technique is employed to siftly roughen certain areas or create an even texture over the whole surface.
Sandblasting that is controlled- Sandblasting can be controlled by intensity the duration, angle, and intensity of application to achieve varying textures or the appearance. Different abrasives and pressure levels result in different outcomes.
Why you should sandblast
The process of sandblasting enables the creation of various textures or surfaces such as mattes, frosted or rough surfaces. This adds an aesthetic appeal and adds unique characteristics to the coins or the medals.
Aesthetic Enhancement - Sandblasting alters the appearance of the surface by diffusing light reflection and reducing shine, which may enhance the coin's or medal's visual appeal. Matte finishes are a fantastic way to highlight design elements.
Anti-Glare Properties - The matte or textured surfaces produced by sandblasting reduce reflection and glare, making metals and coins more pleasant to look at and more attractive.
Contrasting Design Elements- Sandblasting creates contrast between polished and textured areas of the medal or coin and medal, highlighting specific design features or creating depth and dimension.
Sandblasting can be customized, which includes artistic expression as well as the creation of unique medals or coins with finishes or textures customized to meet specific design requirements.
Sandblasting can be a diverse technique used to create various texture or surface finishes on gold medals or coins which contribute to their appearance, and overall design.

How Is Gold Fed Through The Coin Presses And Then Stamped Under High Pressure During Minting?
In the process of coining the gold blanks are loaded into coin presses under high pressure and then stamped to make finished medals or coins. This is a brief overview of the steps involved in loading blanks
In the feeder system connected to the press, the gold blanks have been previously prepared and quality-tested. The feeder system ensures an ongoing quantity of blanks for the coin press.
Feeding Blanks into the Press-
The feeder system is able to guide the blanks one at a time into the chamber of striking for the coin press. This guarantees the exact placement of each stamping blank.
Alignment and Positioning-
In the press, the blanks need to be perfectly placed in the striking area, so that stamping can be completed.
Moving Under High Pressure
The coin press applies high pressure onto the gold blanks using a pair of dies--one stationary and the other moving. The stationary die is the impression of the design that is negative, while the moveable die is the Hammer.
The moving die strikes the blank with a significant force, transferring the image onto the blank's surface. Die presses the design and create relief raised on the coin or medal.
Repeated Striking
To create designs or images that are more sharp and clearer, multiple strikes can be applied to premium coins or editions of collectibles. Each strike improves the fine details of the outside of the coin.
Collection and Ejection
After they have been struck, the newly-minted coins or medals are removed from the press and placed in containers or trays. The designs that are stamped are examined for quality and ensure they conform to the standards set by the manufacturer.
Post-Processing-
According to the specifications for mint design, coins and medals can undergo additional treatments, such as edge lettering or reeding or post-strike treatments.
The stamping process under high pressure is essential as it transfers the desired design onto the gold blanks and transforms the blanks into finished pieces of gold ready for circulation, collection, or for commemoration. The process of stamping demands preciseness as slight the variations in pressure and alignment could influence the final product's quality.
