Challenge coins are coins or medallions that are designed by military units and often carried by the troops. They are often given to troops when they join a unit or earn one in recognition of extraordinary service or other honors.
The Maine Troop Greeters have been honored to receive these challenge coins by our troops as they come through the Bangor International Airport and donate them to our collection. We currently have over 5,000 of these wonderful coins on display in the Troop Greeter Room. They are all being carefully cataloged and photographed, by some of our Maine Troop Greeters. They will eventually be put into a database which will be searchable and available on this web page.
