Found this beauty in a home in Kane County Illinois. It was only a few inches deep and rang up in the mid 50s to low 60s on my AT PRO. It has a Scoville waterbury mark on the back and is a two piece button. Not sure how to clean it up a bit or if at all but I did give it a light brushing with soap and water. It was such a shock to find it in this area. I also found another military button at the home as well it is the black MG crossed rifles button in the multiple items of other things found at the same home pic. I believe it is also from the early 1900s? You button guys can let me know what I have here. Is the Cavalry button from the Civil war or is it an Indian wars button from a later day. I am still shocked to have found such a cool item here in Illinois.
