I read a thread regarding button backmarks that was started in January. I considered just posting to that thread but I didn't want to disrespect the Original Poster by hijacking his thread with my stuff. I found a flat button in a yard where there has been dug over a hundred Civil War Union bullets of various types. Mainly...58 cal Minie's, 52 cal Sharpos Carbine, 69 cal Minie's, and a few round balls. And then this button comes along. I am reluctant to say that it is of Civil War vintage (Union troops occupied my Tennessee town in 1862.....in the spring). There is evidence of an old home here, possibly from that same period. There are pieces of red brick and square nails in this vacant lot....remnants of a dwelling of some sort, and the pieces of brick and square nails go down several inches. But that doesn't really tell me anything about this button. It could have belonged to an ocupant of the house. I remembe, in that other thread about Flat Buttons, that the button could provide clues as to WHERE it was made. Whether London England, or here in the States. Then mention was made of an Eagle being in the backmark. I assume, for that inference, that an Eagle being in the backmark would indicate that the button was made here in the US. What I really wonder about, is if it is possible to get some kind of date (within a decade or so) of when this button would have been manufactured and/or in use. By the way, hello to everyone. This is my first post but I have been a lurker and gleaned alot of good information here regarding this obsession that we love so much. And I appreciate all of that information.
