Introducing a Can’t Stop the Serenity first! This 10th anniversary commemorative challenge coin celebrates 10 years of charitable shindigs across the globe. Die cut from solid brass and finished in antique silver, they’re hefty in the hand, each weighing slightly more than an oz. They are 1.56″ in diameter and about 1/8″ thick. There will never be another printing of this design.
Challenge coins are a military tradition. Here’s the basic idea:
“The challenge, which can be made at any time, begins with the challenger drawing his/her coin, and slapping or placing the coin on the table or bar. In noisy environments, continuously rapping the challenge coin on a surface may initiate the challenge. (Accidentally dropping a challenge coin is considered to be a deliberate challenge to all present.) Everyone being challenged must immediately produce the coin for their organization and anyone failing to do so must buy a round of drinks for the challenger and everyone else who has their challenge coin. However, should everyone challenged be able to produce their coin, the challenger must buy a round of drinks for the group.” – Wikipedia
