A planchet is a small, flat piece of metal, usually circular, that is used as the blank for a coin.
Here's how planchets are used:
1. Preparation: The metal for planchets is typically refined and alloyed to create the desired composition for the coin.
2. Punching: The metal is then rolled into thin sheets and punched out into individual planchets using a specialized die. The die creates the shape and size of the coin.
3. Minting: The planchet is then placed in a coin press, where it is struck by a die with the design of the coin. This creates the raised image and lettering on the coin.
4. Finishing: After minting, the coin may undergo additional finishing steps like polishing, cleaning, or annealing to improve its appearance and durability.
In short, planchets are the blank pieces of metal that are transformed into coins through the minting process.
