The Shield Two-Cent coin, minted in the United States from 1864 to 1873, is notable for being the first U.S. coin to bear the motto "In God We Trust." The 1866 issue is particularly significant due to its early production in the series. The coin features a shield on the obverse and a wreath with the denomination on the reverse. Collectors value the Shield Two-Cent piece for its historical context and unique design elements, making it a popular choice among numismatists.
