I believe I may have found a tombac button,however I'm not really sure.I also found an iron disk,approx the size of a nickle and as thin as a dime,it is very pitted and corroded.I think i may also have found a heel plate,it was found in a colonial cellar hole. thank you for any help you can provide.sorry about the quality of the pictures
