Collectible coins, especially in the context of the United States, encompass various types including So-Called Dollars, which are medals that represent a dollar denomination or commemorative events. The Hibler and Kappen reference is associated with a catalog that details these types of coins, including their designs and historical significance. The "1853" issuance year may relate to specific examples of currency or commemorative coins from that time period. These collectibles often have numismatic value based on rarity, historical importance, and condition.
