How Are Gold Blanks Put Into Coin Presses To Be Stamped Under The Pressure Of High During Minting?
When minting, gold blanks have to be loaded into coin presses and stamping at high pressure in order to create finished awards or coins. Here's a brief outline of how to load blanks.
A feeder system is attached to the coin press. The system loads gold blanks that have been prepared and checked for quality. The feeder system is responsible for maintaining a continuous flow of blanks to the machine.
Feeding Blanks into the Press
The feeder system feeds the blanks into the striking chamber inside the coin press one at a time. This ensures the exact placement of each blank before stamping.
Alignment, Positioning and Positioning
Inside the press, blanks are aligned before being placed in the striking chamber to ensure that they are completely centered and aligned to allow for the stamping process.
Moving Under High Pressure
A coin press applies pressure on gold-plated blanks with two dies, one stationary and the other moving. The stationary die makes an impression of negatives on the shape of the coin, whereas the one that moves is the hammer which strikes the blank.
The moving die hits the blank with a lot of force and then transfers the design on the surface of the blank. The pressure of the dies imprints the designs, which result in the raised reliefs and the details of the medal or coin.
Striking repeatedly is optional.
Multi-strikes are a great option for higher-quality medals or coins for example, like proofs or collector's editions. This will result in an improved and clearer appearance. Each strike refines the detail within the blank.
Ejection & Collection
Following the press's operation, newly-minted coins or medals are released from the press onto containers or trays. The stamped designs are inspected to determine if they are in line with the specifications.
Post-Processing-
If the mint requires it, they could apply additional processes, such as edge lettering, reeding the edge, or post-strike treatments.
The use of high pressure to stamp, which imparts a design on the gold blanks is vital, as this transforms them into finished coin or medals that are used for collectors, circulation or commemoration. This process is highly precise as any alteration in pressure or alignment could impact the quality of the final piece.
