Collectible coins are often categorized based on various factors, including historical significance, rarity, condition, and demand among collectors. In the United States, collectible coins can include series like the Lincoln penny, Standing Liberty quarter, and various commemorative issues. Specific coins, such as the 1915 Jankovsky, may possess unique characteristics or artistic designs that appeal to niche collectors. Additionally, "slugs," which are often used in the context of informal or homemade tokens, differ from traditional currency in that they may lack official backing or wide recognition. The value of collectible coins often fluctuates based on market trends and collector interest.
