The Three-Cent coin, also known as the "trime," was minted in the United States from 1851 to 1873, primarily intended to facilitate small transactions. In 1867, trial coins or patterns were produced in Philadelphia, showcasing various designs and compositions intended for the potential future minting of the denomination. These trial coins are particularly sought after by collectors due to their limited mintage and historical significance, often featuring unique attributes that differ from regular issue coins. Collectors value these patterns for their artistry and the insight they provide into the minting process of the era.
