Collectible coins encompass a wide range of items, including historical, rare, and unique pieces from various cultures and time periods. In the context of the United States, collectible coins often feature iconic designs and significant historical events, attracting both numismatists and casual collectors. Slugs, such as those produced by Jankovsky in 1920, refer to coins that have been struck without legal tender status, often created for novelty or promotional purposes. The term "Unknown" may indicate coins whose origins, minting details, or historical context are not well-documented, making them intriguing to collectors seeking to uncover their story.
