Military Coins Detail
A challenge coin is a small coin or medallion (usually military), bearing an organization’s insignia or emblem and carried by the organization’s members. Traditionally, they are given to prove membership when challenged and to enhance morale. In addition, they are also collected by service members. In practice, challenge coins are normally presented by unit commanders in recognition of special achievement by a member of the unit. They are also exchanged in recognition of visits to an organization.
There are several stories detailing the origins of the challenge coin. According to the most common story, challenge coins originated during World War I. American volunteers from all parts of the country filled the newly formed flying squadrons. Some were wealthy scions attending colleges such as Yale and Harvard who quit in mid-term to join the war. In one squadron, a wealthy lieutenant ordered medallions struck in solid bronze and presented them to his unit. One young pilot placed the medallion in a small leather pouch that he wore about his neck.
