A challenge coin is a small coin or medallion (usually military, but also police, fire and other services), bearing an organization's insignia or emblem and is carried by the organization's members. They are given to prove membership when challenged to prove membership.In addition to using challenge coins for challenging, they are also used as rewards or awards, and as a tool to build morale. In the modern U.S. military, the tradition most likely began among Special Forces units during the Vietnam War then spread to the Airborne troops, and a little later to the 75th Infantry Rangers. As officers were reassigned through their careers, they continued the tradition of awarding a unit coin for acts that were worthy of recognition but did not qualify the person for an official medal. Challenge Coins were not very common until the First Persian Gulf War and since then their popularity has grown significantly in the military as well as among other uniformed services for the most part.The design for the Dougas County Sheriff’s Department SWAT team illustrates the wonderful level of artistic detail that can be incorporated into a challenge coin.The process begins witha sketch-up of the desired design for the coin.... which is then worked intothe final artwork that will goto the die casting process.... returning as the finishedchallenge coin.
