Collectible coins encompass a wide range of types, including historical, commemorative, and error coins, each appealing to different collectors based on rarity, historical significance, and condition. The term "Slugs" can refer to large, flat tokens or coins that are often created for specific purposes or as novelties. The Jankovsky coinage from 1920 may represent an individual designer's output or a specific issue from that year, notable in the context of American numismatics. Collectors assess these coins based on their provenance, minting details, and market demand.
