Materials needed for manufacturing coins are displayed here. First, multiple metals from different kinds of coins are melted between 1,000℃ and 1,200℃ and made into coin blanks. Next, the coin design is cut into plaster plates. Pour synthetic resins to the plaster plates to make hard resin plates in advance to strike the coin blanks. Make the original die, a coin mold, with the hard resin plates. Then, produce the working die, a coining press, based on the original die. Lastly, pressing the working die on the coin blanks makes new coins.
