Collectible coins can include a variety of types such as historical, commemorative, and error coins. The United States has produced notable collectible coins, including the 20 Dollar gold pieces, often referred to as "double eagles." The 1895 issue is particularly prized among collectors for its rarity and historical significance. Coins related to Hawaii may hold additional value due to the islands' unique history and connection to U.S. statehood. The term "unknown" could refer to coins with unidentified mint marks or variations that require further research for proper classification.
