Collectible coins encompass a variety of types, including patterns, trial coins, and commemorative issues. In the United States, collectible coins are often sought after by numismatists for their historical significance, rarity, and unique designs. Trial coins, such as those produced in 1979, are typically experimental pieces created to evaluate designs or production methods before mass production. These coins can vary in composition and may not be issued for general circulation, making them particularly valuable to collectors.
