For the last two decades, the Highland Mint in Melbourne has made the coin that will decide which team kicks off or receives on Super Bowl Sunday.

It is a responsibility management at the company said no one takes lightly.

"We take great pride in being part of this game," Vincent Bohbot, the Executive Vice President of the company said.

The coin begins as one large piece in a large furnace. Then, the metal gets cut into blanks and the Super Bowl image has to be stamped on the coin, inspected and cleaned. Finally, a serial number is written on the coin to match the documents that come with the coin.

The first 100 coins go to the Super Bowl. The coin used in the coin toss goes to the Pro Football Hall of Fame as part of its Super Bowl dispay. The next 99 coins are given to players and dignitaries. The company says 9,900 other coins are sold to the public for $100.

An estimated 170-million people are expected to watch the big game.
