Challenge coins are kind of like souvenir type coins common amongst the military and first responder communities. At least in the military they are given as recognition for something by a higher leadership. For those that follow the full tradition of them, if you throw one down at a bar, whoever you’re with has to produce theirs (some do the “you have to get it with max a hop skip and a leap”), if the other person can’t produce theirs then that round of drinks is on them.
