Coin Mints

• Long ago, coins were made out of precious metals
  like gold and silver. Today, coins are usually
  made out of other metals.
• When mints make coins today, they are not made of
  gold or silver. They are made from a mixture of
  copper and nickel, called an alloy. These metals
  are cheaper and more available than the other
  precious metals.
• To make them, the metal is melted and poured into
  molds to make bars or ingots. Machines roll the
  ingots into sheets. Blanks for each type of coins
  are punched out from the sheets. They are then
  put through an edge-rolling machine, which
  produced a raised rim or an edge on each coin.
  Finally, the designs are stamped onto both sides
  at the same time.
• All coins made in the United States have two
  sayings stamped on them. One of them is "E
  Pluribus Unum" - Latin for "Out of many, one."
  The other saying is "In God We Trust." When the
  coins are finished, they are counted and weighed
  and sent in bags to banks.
