I dug this over a bank at a Union Civil War campsite. It is 2 inches is diameter, 1 inch high at the center. It appears to be made of bronze or brass. On the bottom is some chinese symbols and I was hoping someone could translate it or tell me where I can send the pictures to have it translated. My research shows that it could possibly be a censer (incense burner). My question is, why was it on a civil war campsite.
