The Shield Two Cents coin, issued in 1864, was one of the first U.S. coins to bear the motto "In God We Trust." The 1873 variation includes distinct design elements, such as the shield motif and a unique reverse featuring a laurel wreath. The Three Dollar gold piece, introduced in 1854, was primarily produced for gold transactions and is known for its rarity and high demand among collectors. These coins symbolize significant periods in U.S. numismatic history and hold considerable value for collectors.
