The Mysterious and Fascinating History of the Military Challenge Coin

When most people think of coins, they think of the kind they can use as legal tender. The nickels, dimes, quarters, and similar discs of metal that are decorated with dead historical figures (usually a former US president) and a variety of other American symbols. Pieces of physical currency worth a certain number of cents that folks store in jars or carry in their pockets, purses, etc. But those of us in the military community know of a different type of coin, coins that some collect by the dozen.

And while you can’t use them to feed a parking meter or a vending machine, these scraps of metal hold varying values of a different kind. We speak, of course, of challenge coins. And while you’d be hard-pressed to find a servicemember of any branch who doesn’t own at least one, not every one of them knows the full history behind the tradition of military challenge coins.

The Origins of the Formal Military Challenge Coin

While tokens signifying service in a particular war or under a particular commander date back thousands of years, the origins of modern military challenge coins date back to World War One. Those origins are murky to say the least, more myth than confirmable truths. And there is more than one story explaining how it all began. But the most widely circulated and believed of those stories begins with a well-to-do young US Army aviator who served in the Great War and whose identity time forgot in the ensuing decades.

Legend has it that this unnamed Army pilot wanted to honor all of the fellow soldiers, officers, and enlisted personnel serving in his unit. As such, he used his wealth to commission medallions imprinted with the unit insignia for all of them. At some point, the Germans shot down and captured him, after which they stripped him of all his personal belongings save a necklace he wore with a pouch containing his own copy of the medallion.

After escaping his captors and donning stolen clothes, he managed to make it back to Allied lines, where the French troops he encountered assumed the man in civilian duds speaking a foreign language was an enemy spy trying to infiltrate their position.

His execution imminent, the pilot presented his suspicious allies with the medallion bearing his unit insignia. Taking it as sufficient evidence that he was who he claimed to be, the French freed their mistakenly taken prisoner (with, according to some versions, a bottle of brandy or wine as an apology for nearly shooting him dead) and returned him to his squadron. In order to avoid similar issues of mistaken identity, the members of the American’s unit took to carrying their medallions with them at all times. And that, as the tale goes, is the origin of the military challenge coin.

Now, just how much of that is true is a matter of no small debate. After all, who exactly was this mysterious, rich Army aviator? What squadron did he fly with? And how was its insignia and coins emblazoned with it so recognizable that it kept a French firing squad from putting him to death? To say nothing of the other possible origin stories which trace the first military challenge coins to the Vietnam War and the 1960s. But whatever their true origin, these coins have become commonplace pieces of American military memorabilia.

The Evolution of Military Challenge Coins

From those unclear origins, the issuing of challenge coins spread not as any sort of official policy but as informal barracks tradition. Some accounts point to the aforementioned Vietnam-era origins as the same time when the modern “coin check” custom truly took shape, originally among Special Forces units.

Some accounts date the start of this modern-day coin practice to 1969 with the 10th Special Forces Group during the Vietnam War, while the Department of Defense emphasizes that the exact beginnings of these traditions were impossible to pin down because of their originally informal nature. In other words, challenge coins evolved in the same way many military traditions do: passed with changes from one unit to another and ever evolving to reflect the histories of different branches and units.

By the late twentieth century, coins were no longer limited to small flying squadrons or special operations circles. Unit commanders, senior enlisted leaders, ships, battalions, wings, task forces, and even temporary deployment groups began minting their own designs. The reasons for handing them out expanded as well.

A coin could mark membership in a unit, commemorate a deployment, recognize excellent performance, or simply preserve the memory of a shared hardship. One of this particular writer’s best friends once received one from a Commandant of the Marine Corps for asking the general a particularly pertinent question during a lecture to us as our cohorts back when we were a horde of baby-faced second lieutenants.

Military Challenge Coins Today

Today, military challenge coins are part keepsake, part symbol of recognition, and part handshake-sized history lesson. They are often presented to recipients quietly and personally rather than through formal, public ceremonies. A senior commander palms one to a subordinate to recognize a job well done.

A high-ranking individual gives a few out to the deserving during a base visit. A unit produces one to commemorate a deployment, anniversary, exercise, or change of command. The Department of Defense describes them as a tradition meant to instill unit pride, improve esprit de corps, and reward hard work and excellence, which is why a coin from a respected leader or a meaningful mission can carry emotional weight far beyond the value of the metals used to mint it. A challenge coin reminds its owner of important aspects of their service, an inanimate echo of phrases like “You were there,” “You belong,” or “Your work mattered.”

That is why so many Veterans and service members keep them on desks, in display cases, or tucked away alongside medals, patches, and photographs. A challenge coin may lack any monetary value, but for the person who earned it, received it, or traded it, its value is beyond measure.
