How Does Gold Get Through The Coin Presses, And Then Stamped Under High Pressure While Minting?
In the process of coining the gold blanks are loaded into coin presses at extreme pressure. They are then stamped to produce finished medals or coins. Here is an outline of how to load blanks.
Loading gold-plated blanks into a feeder that is connected to the coin press takes place after they've been prepared, inspected and evaluated. This feeder system is accountable for maintaining a continuous flow of blanks to the coin press.
Feeding Blanks into the Press
The feeder system introduces blanks into the striking chamber inside the coin press one at a. The feeder system guarantees that each blank is placed precisely for stamping.
Alignment and Positioning
The blanks inside the press chamber are placed, aligned and perfectly oriented to ensure that they are stamped.
Striking in High Pressure
The coin press presses the gold blanks with the highest pressure using two dies: one stationary and another moving. The stationary die is equipped with negative designs that are made on the coin, while the moving die is used to strike the blank.
Die dies hit the blank with lots of force, which transfers the design onto the surface. The force exerted by dies creates the design, creating the relief that is raised as well as specifics on the coin or medal.
Repeated Striking
Multi-strikes can be applied for higher-quality medals or coins for example, like proofs or collector's editions. This results in more precise and sharper appearance. Each strike improves the design of the blank's surface.
Ejection and Collection
The coins or medals will be ejected and placed in containers or trays after they have been struck. They are checked to ensure quality control and make sure that the designs are in line with all requirements and standards.
Post-Processing-
If the mint specifies it, they may also apply additional processes, such as edge lettering, reeding the edge, or post-strike treatment.
The high pressure of stamping imparts the desired designs onto gold blanks, changing into finished coins or medals that are ready for use in collections, circulation or even commemoration. This process demands precision, since any slight variation in alignment or pressure can impact the appearance and quality of the final product.
