One of the popular uses of custom souvenir challenge coins is to commission them as unique commemorative items for an event, business, or famous location. As souvenirs, challenge coins are unique gifts marking a visit to a famous location or as a keepsake of a major event. These items can become very popular with travelers and collectors, marking the sites they’ve visited and commemorating major events they may have witnessed. As memorabilia, souvenir challenge coins can be commissioned in small orders, perhaps to only the first 1,000 visitors of a location or only sold to attendees at certain events. Limited-runs make specific souvenir challenge coins highly demanded items and even draws a collector’s interest to attend events partially out of an interest in collecting a unique souvenir challenge coin. Often, major businesses and organizations will also commission unique challenge coins representing their place of business or operations.
