There are many examples of traditions that build camaraderie in the military, but few are as well-respected as the practice of carrying a challenge coin—a small medallion or token that signifies a person is a member of an organization. Even though challenge coins have broken into the civilian population, they’re still a bit of a mystery for those outside the armed forces.
What Do Challenge Coins Look Like?
Typically, challenge coins are around 1.5 to 2 inches in diameter, and about 1/10-inch thick, but the styles and sizes vary wildly—some even come in unusual shapes like shields, pentagons, arrowheads, and dog tags. The coins are generally made of pewter, copper, or nickel, with a variety of finishes available (some limited edition coins are plated in gold). The designs can be simple—an engraving of the organization’s insignia and motto—or have enamel highlights, multi-dimensional designs, and cut outs.
It’s nearly impossible to definitively know why and where the tradition of challenge coins began. One thing is certain: Coins and military service go back a lot farther than our modern age.
One of the earliest known examples of an enlisted soldier being monetarily rewarded for valor took place in Ancient Rome. If a soldier performed well in battle that day, he would receive his typical day’s pay, and a separate coin as a bonus. Some accounts say that the coin was specially minted with a mark of the legion from which it came, prompting some men to hold on to their coins as a memento, rather than spend them.
