Collectible coins encompass various categories, including historical coins, error coins, commemorative issues, and trade tokens. Trade tokens, such as those cataloged by Rulau, were often used in local commerce during the 19th and early 20th centuries as substitutes for currency. The year 1867 marks a significant period in U.S. coinage history, reflecting the expansion of commerce and the use of tokens. Unknown coins may refer to pieces for which little historical information is available, adding an element of mystery and intrigue to the collecting hobby.
