Challenge coins, originally a military tradition symbolizing camaraderie and unit identity, were adopted by motorcycle clubs post-World War II, many of which were founded by veterans. These clubs create unique challenge coins representing membership and loyalty. To display these coins, handmade wooden boards are used, reflecting the same pride and craftsmanship as the coins themselves. These boards serve as functional art, showcasing collections, commemorating significant events, and preserving club history and traditions. They symbolize brotherhood, respect, and shared experiences among club members.
