How And Why Are Some Surfaces Or Textures That Resemble Matte Or Textured Surfaces Created By Sandblasting?
Sandblasting can produce textured or matte surfaces on gold coins and medals. This is the reason and how it's usedProcess for Sandblasting
Surface preparation: The coin is placed inside a box or cabinet that is equipped with an air compressor as well as an spray nozzle. The chamber is typically enclosed in order to keep the abrasive used to prepare the surface.
The medal or coin is then sprayed with an abrasive material, which could comprise glass beads, sand silicon carbide, or aluminum oxide.
High-Pressure propulsion - Abrasive particles are delivered to the surface of the surface by with compressed gas or a different high pressure system. The surface texture is created by the force and speed of the particles.
Texture Creation: The force from the abrasive grains on the surface results in the appearance of a matte or textured by altering the topography of the surface. This process lets you roughen specific areas or to create a texture that is consistent across the surface.
Sandblasting can be controlled in terms of intensity, duration, and angle controlled, resulting in different textures or finishes. Different abrasives are used to create different effects.
Sandblasting is a reason why it's done
Texture Variation- Sandblasting allows to create various types of textures and finishes including matte and frosted surfaces that add the appearance of interest and distinct characteristics to the coins or medals.
Aesthetics Enhancement – Sandblasting can alter the appearance of the surface, diffuse light reflection, and even reduce shine. This improves the value of the coin or medal's aesthetic appeal. Matte surfaces, such as those that reduce glare, can highlight specific design details.
Anti-Glare: A matte or textured finish that is created by sandblasting will reduce reflections or glare. This makes the medals or coins appear more appealing, and they are more easily read with no unwanted light interference.
Sandblasting Produces Contrasting Design Elements Sandblasting creates contrast between the texture and polished areas on the medal or coin, highlighting particular design elements or creating visual depth.
Sandblasting offers a variety of customization options that permit artistic expression and allows coins or medals to be designed with different distinct textures or finishes that are unique to the design.

How Is Gold Fed Through The Coin Presses, And Then Stamped Under High-Pressure During Minting?
During the coining process, blanks of gold are loaded into coin presses under intense pressure. Then, they are stamped to make finished medals or coins. Here's a brief outline of the process for loading blanks.
Incorporating gold blanks into a feeder that is connected to a coin press is done after they've been cleaned, inspected and graded. This feeder makes sure that blanks are constantly delivered to the machine.
Feeding Blanks in the Press
This feeder system makes sure that each blank is placed precisely inside the chamber of stamping. This ensures the exact placement of each blank before stamping.
Alignment and Positioning
The blanks are positioned and aligned in the chamber for striking of the press to ensure that they are perfectly aligned to be used for stamping.
Striking Under High Pressure
Coin presses put massive pressure on gold blanks with a pair dies -- one stationary and one mobile. The stationary die contains the negative image of the design of the coin, while the die that moves acts as the hammer that strikes the blank.
The moving die transfers the design of the blank to its surface with a great deal of force. Die dies pressurize the design to create the relief that is raised on the coin or medal.
Repeated Striking
In order to create an image or design that is more sharp and clearer, multiple strikes can be used on rare coins or collectible editions. Each strike improves the surface characteristics of the blank.
Ejection and Collection
After being struck, 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 meet specified standards.
Post-Processing-
According to the specifications for mint design the coins and medals could be subjected to additional treatments like edge lettering or reeding or post-strike treatment.
The stamping process under high pressure is essential because it imparts the desired design to the gold blanks, transforming them into finished pieces of gold ready for use in collection, circulation, or for commemoration. Precision is required, as even the slightest deviation in the pressurization or alignment of the gold-plated blanks may result in a negative impact on the appearance and quality of the finished product.
