Collectible coins can encompass a variety of types, including historical, commemorative, and artistic pieces. Within the United States, coins such as the 1906 Jankovsky slugs represent unconventional forms that may be sought after by niche collectors. These slugs are often considered "other varied" items, differing from standard currency due to their unique designs or purpose. Collectors value such coins for their rarity, historical significance, and aesthetic appeal, contributing to the diverse market of numismatics.
