Just compare the details to the coin posted by wlb42, look carefully at the postion and shape of the letters, numbers and the main devices. While at a glance it may look similar, almost everything is just a little bit different. There is zero chance this is an original, and money spent getting it graded would be wasted. Copies have no real value so it would be money wasted. Certainly show it to a coin dealer if you wish, but I sure wouldn't spend the money to have it authenticated. Having been found near a battlefield would not be a plus either, as none of the originals were ever issued, and none came to light until years after the Civil War. The few that were made supposedly stayed in the possession of Lovett, the minter, until he accidentally spent one. The story goes that he then sold the few pattern pieces that he made. Fakes have been available in souvenier shops and the like for at least sixty years, so there is plenty of time for a fake to have aged. Hate to be a downer, but just my opinion.
