Since 1991, the Maine Troop Greeters at Bangor International Airport has hosted over 7,000 military flights and more than a million United States troops returning home from overseas deployments.  In the Troop Room and Greeter Museum, visitors will find more than 6,000 unique challenge coins donated by troops while passing through the airport.

Challenge coins are not currency, they are large medallions and customized coins used by the military for special recognition of relationships, extraordinary service, or achievement.  Many military units mint these custom coins to commemorate their unit history and shared experiences overseas.

When they’re being given or exchanged, the coins serve as tokens of gratitude and appreciation.
