The game doesn't start without the flip coin used by the referee for each games official coin toss. The Flip Coin for the game at Frankfurt Stadium in Germany between the MIami Dolphins and the Kansas City Chiefs is silver plated and it measures 39mm in diameter. It's minted with the dueling team logos embedded in color in the center of the obverse and the NFL shield on the reverse. Each coin is individually numbered on its edge, protected in a clear capsule to preserve its condition and accompanied by a certificate of authenticity. This coin is a limited edition of only 5000 and it's officially licensed by the NFL making it a true collectible. Proudly made in the USA by The Highland Mint!
