Collectible coins encompass various types, including numismatic items valued for their rarity, historical significance, and condition. In the United States, the dime, worth ten cents, has several notable issues, one being the Mercury Dime, minted from 1916 to 1945. The 1934 Mercury Dime is particularly sought after by collectors, with its design featuring a depiction of Liberty, and is often collected for its potential value based on mint mark, condition, and market demand.
