The US Mint is responsible for the manufacturing of coins and is also considered the largest mint in the World. The Us Mint has different locations. The Philadelphia Mint (founded in 1792) manufactures 30 million coins daily!
Before a coin can be produced, it must go through a series of steps. First, a group of artists from the US Mint draw the coin design. Then, sculptors generate large models of the coin out of clay and then plaster and modify the details by hand. This is a tedious process and will enhance the design and make the coins harder to forge. Since the plaster model is very delicate, it is covered with rubber and later used to make an epoxy design. The sculpture will be reduced to size and onto a master hub made out of steel. This master hub is used to make the master dies and can then be use to stamp the images on the coin.
The process of minting coins is tedious and meticulous. A small error can make a coin very valuable. One example is the 1955 doubled die Lincoln Wheat Cent, where a doubled die was used and it caused the design to overlap.
