How Is Gold Fed Into The Coin Presses, And Then Stamped With High-Pressure During Minting?
During the minting process gold blanks are loaded into coin presses, where they are stamped under extreme pressure to make into finished pieces of gold or coins. This article provides a brief description of the steps in loading blanks.
The loading of gold-plated blanks into a feeder connected to the coin press takes place after they have been prepared, inspected and assessed. This feeder system assures a steady flow of blanks.
Feeding Blanks into the Press-
The feeder system directs the blanks one at a time into the chamber of striking for the coin press. The feeder system guarantees that every blank is precisely placed to allow for stamping.
Alignment of Position
Within the press, the blanks are aligned and positioned in the striking chamber, ensuring that they are completely centered and aligned for the stamping process.
Striking at High Pressure
Coin presses put high pressure on the gold blanks with two dies - one stationary and the other mobile. The stationary die leaves a negative impression on the shape of the coin, whereas it is moving that die acts as the hammer which strikes the blank.
The die that is moving strikes the blank with great force and then transfers the design on the surface of the blank. Die dies pressurize the design, resulting in relief that is raised on the coin or medal.
Repeated Striking Optional
To create designs or images that are sharper and clearer, multiple strikes can be used on rare coins or collectible editions. Each strike refines the design of the surface of the blank.
Ejections and Collection
Once struck, the newly-minted coins or medals are released from the press, and then placed in trays or containers. The designs that are stamped are examined for quality control in order to make sure that they meet the standards and requirements.
Post-Processing-
If the mint has specified it, they could apply additional procedures for edge lettering, reeding the edge, or post-strike treatments.
The process of stamping gold blanks using high pressure is vital since it transfers the desired design to the blanks of gold. Then, they are transformed into finished gold coins or medals ready for collection, circulation or for commemoration. This process requires precision since any slight variation in alignment or pressure can impact the appearance and quality of the final product.
