Patterns are experimental or trial coins struck to test designs or compositions before final production. In the United States, the 1852 pattern coins were created as part of an effort to redesign existing currency, often featuring unique designs that never made it into general circulation. These coins are highly sought after by collectors due to their rarity and historical significance as they represent transitional phases in American coinage.
