The planchets are fed into the coining chamber where the press will strike coins at a rate of up to 720 per minute. The coining chamber includes an upper and lower die and a collar. A great deal of pressure brings the dies in contact with the planchet, leaving their impression. The collar keeps the planchet round. Once the planchet is struck, it is now officially a coin and is ejected from the coining chamber as new planchet takes the coin’s place.
Now it is up to the Mint to make a uniform product.
