Collectible coins can be categorized into various types, including traditional coins, medals, and other varied items. Coins typically refer to currency issued by a government, while medals are often commemorative pieces that honor a person, event, or achievement. In the United States, collectible coins can include both historical and modern issues, with notable examples from specific years like 1993. The term "unknown" may refer to coins or medals whose origins, minting details, or purposes are not well documented, posing unique challenges and opportunities for collectors.
