A challenge coin is a small, custom-made metal token typically issued to members of military units, law enforcement agencies, fire departments, or corporate teams as a symbol of membership, achievement, or camaraderie. Recipients often carry them at all times and may participate in “coin checks” — informal challenges to prove membership.
A commemorative coin, on the other hand, is created to honor a person, event, anniversary, or organization — such as weddings, retirements, national holidays (like Christmas), or historical milestones. While not legal tender, these coins are collectible keepsakes with sentimental or decorative value.
Both are made from durable metals like brass, zinc alloy, or copper, and feature detailed designs through enamel coloring, engraving, or 3D sculpting. Unlike currency, they’re used for recognition, gifting, and legacy-building.
