Minting is the process of creating a die-struck coin by striking a metal blank between two dies.

The obverse die is the die that strikes the face of the coin, while the reverse die is the die that strikes the back of the coin.

The collar is a ring that surrounds the coin blank and prevents the metal from flowing out of the dies during striking.

Reeding is the term for the small raised lines on the edge of a coin.

Annealing is the process of heating and cooling the metal blank to soften it and make it more malleable.

Trimming is the process of removing excess metal from a coin blank to create a round, uniform shape.

Finishing is the process of cleaning and polishing a coin after it has been struck to remove any remaining impurities and to create a smooth, shiny surface.

Numismatics is the study of coins and other forms of currency.

A double strike is a coin that has been struck twice by the dies, resulting in a misaligned or incomplete design.

An underweight coin is a coin that has been struck on a blank that is too small, resulting in a coin that is lighter than its intended weight.

An overweight coin is a coin that has been struck on a blank that is too large, resulting in a coin that is heavier than its intended weight.

An off-center coin is a coin that has been struck off-center, resulting in a design that is not centered on the coin.

A capped die is a coin that has been struck with a die that has a broken or damaged design, resulting in a coin with a missing or incomplete design.

A rotated die is a coin that has been struck with a die that has been rotated, resulting in a design that is rotated on the coin.

A misaligned die is a coin that has been struck with a die that has been misaligned, resulting in a design that is not properly aligned on the coin.
