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. 
              
Shortly after acquiring the medallions, the pilot's aircraft 
                was severely damaged by ground fire. He was forced to land behind 
                enemy lines and was immediately captured by a German patrol. In 
                order to discourage his escape, the Germans took all of his personal 
                identification except for the small leather pouch around his neck. 
                In the meantime, he was taken to a small French town near the 
                front. Taking advantage of a bombardment that night, he escaped. 
                However, he was without personal identification. 
              He succeeded in avoiding German patrols by donning civilian attire 
                and reached the front lines. With great difficulty, he crossed 
                no-man's land. Eventually, he stumbled onto a French outpost. 
                Unfortunately, saboteurs had plagued the French in the sector. 
                They sometimes masqueraded as civilians and wore civilian clothes. 
                Not recognizing the young pilot's American accent, the French 
                thought him to be a saboteur and made ready to execute him. He 
                had no identification to prove his allegiance, but he did have 
                his leather pouch containing the medallion. He showed the medallion 
                to his would-be executioners and one of his French captors recognized 
                the squadron insignia on the medallion. They delayed his execution 
                long enough for him to confirm his identity. Instead of shooting 
                him they gave him a bottle of wine. 
              Back at his squadron, it became tradition to ensure that all 
                members carried their medallion or coin at all times. This was 
                accomplished through challenge in the following manner - a challenger 
                would ask to see the medallion. If the challenged could not produce 
                a medallion, they were required to buy a drink of choice for the 
                member who challenged them. If the challenged member produced 
                a medallion, then the challenging member was required to pay for 
                the drink. This tradition continued on throughout the war and 
                for many years after the war while surviving members of the squadron 
                were still alive. 
              All personnel present must present their coin whenever 
                a coin check is initiated. Individual(s) not in possession of 
                their coin during a coin check will be required to purchase a 
                beverage for each individual who produced a coin. If all personnel 
                produce a coin, the individual initiating the check will buy. 
                
              Coin checks are permitted, ANY TIME, ANY PLACE.
