The Shield Two Cents coin, minted in the United States from 1864 to 1873, is notable for being the first circulating coin in U.S. history to be minted in a denomination of two cents. The 1865 Shield Two Cents features a shield design on the obverse, symbolizing protection and strength, with the denomination and the year prominently displayed. This coin was produced in response to a shortage of coins during the Civil War and represents a unique aspect of American numismatic history. The "N A" designation could refer to a specific grading or classification within a numismatic context, indicating the coin's condition or type.
