Challenge Coin Origins
It ’s almost impossible to definitively know why and where the custom of challenge coins begin . One thing is sealed : coin and military service go back a batch further than our modern eld .
One of the earliest make love examples of an enlisted soldier being monetarily honour for valor took topographic point in Ancient Rome . If a soldier perform well in struggle that day , he would obtain his distinctive day ’s pay , and a separate coin as a bonus .

The First Official Challenge Coin…Maybe
Although no one is certain how challenge coin came to be , one history go steady back to World War I , when a wealthy officer had bronze medallions struck with the vaporize squadron ’s insignia to give to his adult male . Shortly after , one of the young flying one was shot down over Germany and entrance . The Germans took everything on his individual except the little leather pouch he wore around his neck opening that materialise to hold back his laurel wreath .
The pilot escaped and made his means to France . But the French believe he was a spy , and sentenced him to execution . In an elbow grease to prove his identicalness , the pilot presented the medallion . A French soldier happened to recognise the insignia and the carrying out was check . The French confirm his identity and mail him back to his building block .

A maw was exercise in the top so the men could bust it around their neck , instead of in a leather pouch .
The Challenge
Stories say that the challenge commence in Germany after World War II . Americans stationed there took up the local custom of conducting “ pfennig check . ” The pfennig was the lowest appellative of coin in Germany , and if you did n’t have one when a hitch was prognosticate , you were stuck buying the beers . This evolve from a pfenning to a unit ’s medallion , and members would " challenge " each other by slamming a medallion down on the legal profession . If any member present did n’t have his palm , he had to bribe a swallow for the challenger and for anyone else that had their coin . If all the other members had their medallions , the challenger had to buy everyone drinking .

It could have its stock in the Second Boer War , oppose between the British and South African colonists at the twist of the 20th century . The British lease many soldiers of fortune for the conflict , who , due to their worldly-minded status , were ineffectual to realize medals of heroism . It was not strange , though , for the commanding officer of those mercenaries to find the adjustment rather . Stories say that non - commissioned officers would often snarf into the collapsible shelter of an unjustly awarded ship’s officer and cut the medal from the palm . Then , in a public observance , they would call the deserving mercenary ahead and , handle the palm , throw off his hired man , passing it to the soldier as a way of indirectly give thanks him for his service .

The first coins from this earned run average were make by either the Army ’s 10th or 11th Special Forces Group and were little more than common currency with the unit of measurement ’s insignia stamped on one side , but the man in the building block carried them with pride .
More importantly , though , it was a lot secure than the alternative — slug clubs , whose member carried a single fresh bullet at all time . Many of these bullets were apply as a reward for outlive a mission , with the estimation that it was now a “ last refuge smoke , ” to be used on yourself instead of surrendering if defeat seemed imminent . Of course carrying a bullet was little more than a show of machismo , so what started off as pistol or M16 troll , soon intensify to .50 caliber bullet , anti - aircraft rounds , and even gun shells in an sweat to one - up each other .
Unfortunately , when these bullet order member presented “ The Challenge ” to each other in bars , it meant they were slam lively ammunition down on the tabular array . disturbed that a deadly accident might occur , command cast out the ordnance , and replaced it with limited edition Special Forces coins rather . Soon almost every unit had their own coin , and some even minted commemorative coins for specially hard - fought struggle to pass out to those who endure to state the tale .
