Challenge coins are  great way to show support for law enforcement.  The beginnings of challenge coins can be traced back to war times for purposes of identification.  Today, their purpose has grown beyond that and they can be used as recognition for special achievements or as a collectible item.  The blue lives matter challenge coin makes for a great gift to an officer and his/her squad for any occasion.
