The coin in question is a Shield Two Cents piece from the United States, minted in the year 1864. Designed by James Barton Longacre, it features a unique design that showcases an emblematic shield at its center, symbolizing protection and strength. This particular coin has a diameter of 23 millimeters and weighs 6.22 grams. Made of bronze, the coin represents a denomination of 2 cents (or 0.02 USD). During its production, a total of 19,847,500 of these coins were minted, indicating it was relatively common in its time compared to other issues. The reverse side features a design that includes two intertwined branches, and the edge is plain, lacking any inscription or pattern. Notably, this coin does not have a mint mark, indicating that it was likely produced in one of the main U.S. mints rather than a branch mint. The Shield Two Cents coin serves as a fascinating piece of American numismatic history, reflecting the economic conditions of the time as the country was in the midst of the Civil War. Collectors value it not only for its historical significance but also for its distinctive design and relatively large mintage, making it a sought-after item for those interested in historical U.S. currency.
