Collectible coins encompass a wide variety of types and categories, including historical coins, commemorative issues, and error coins. In the United States, collectible coins can be found in various denominations and designs, often varying by year and mint location. The term "slugs" typically refers to larger, flat pieces of metal that are sometimes used in coinage or as tokens. The Jankovsky series, dated 1960, may refer to specific artistically designed pieces, though details about their rarity and desirability can vary. Many collectible coins may remain unknown in terms of origin or specific value, making them intriguing for collectors.
