Collectible coins encompass various categories, including commemorative coins, bullion coins, error coins, and trial coins. Trial coins, like those from 1872, are experimental pieces created to test design, composition, or minting processes before official production. In the United States, trial coins can represent significant trials in coinage history and are often sought after due to their rarity and unique characteristics. Collectors value these pieces for their historical context and the insight they provide into the evolution of U.S. coinage.
