Collectible coins typically include a wide range of items, such as ancient coins, numismatic currency, and modern commemoratives. In the United States, collectible coins can encompass various types issued by the U.S. Mint, including limited editions, proofs, and specialty series. The term "slugs" often refers to large or unusual tokens or coins that may not fit traditional numismatic categories. The Jankovsky series from 1950 is a specific collection, and unknown coins can refer to those whose origins or details are not well-documented, making them intriguing for collectors seeking rarity and mystery.
