Wherever warriors gather, they challenge each other by “coining.” The group's unique coin is slammed on a bar to challenge all in the group to display their own coins; she who is last must pay a penalty. Most important, a challenge coin is carried at all times. Putting your coin in someone else's hand during a challenge means that you're giving it to them. Alternatively you can showcase a coin on a table, hold it in the palm of your hand, or hold it up. Anyone who wants to take a closer look at the coin is obligated to bring it back to its spot. Share your Marlin Club Challenge Coin at your local bar to remember your trip to Catalina Island.
