Collectible coins are often categorized based on their historical significance, rarity, and condition. In the United States, Territorial coins are a notable subgroup, particularly those issued before the establishment of a national mint. The 1855 Twenty Dollars coin, often associated with the California Gold Rush, exemplifies this category, as it reflects the early attempts to create a standardized currency in the western territories. These coins are sought after by collectors for their historical context and scarcity, making them valuable within the numismatic market.
