A challenge coin is a coin or medallion bearing an organization’s insignia or emblem and carried by the organization’s members at all times. In addition, they are also collected and traded by members and supporters of other groups and organizations. When challenged, members of the group must produce their coin immediately or pay the consequence of losing the challenge (usually a round of drinks of the groups choice).
I was sent over Los Angeles Kings, Saint Patricks Party 2014 and NYPD CARES. The one that I like the most is NYPD CARES because it’s to fight breast cancer and that is something that means a lot to me. The coins are very unique in their own way and you get how they are made with very high quality. I get into my mom because she likes to collect coins and she said they would make a great addition to her collection.
