Collectible coins refer to specific issued or unissued coins that are sought after by collectors due to their rarity, historical significance, or unique features. In the context of the United States, the 1915 One Dollar coin is particularly notable, as it includes patterns created during the development phases for various coin designs. These patterns are often struck in limited quantities and can be highly valuable in the numismatic market. Collectors seek such items for their artistic merit, historical context, and potential investment value.
