Collectible coins encompass various types, including those minted for circulation, commemoratives, and patterns. In the United States, the 1 One Cent Penny, commonly known as the penny, has several significant varieties. Among these, the 1944 Pattern coins are notable; these were experimental pieces created to test new designs and compositions. Trial coins, like the 1944 Patterns, often have limited runs and are highly sought after by collectors for their rarity and historical significance.
