Hi, in the first picture of this post, in the third row down of buttons, there is one button different than the others. It has a straight shank in the middle in stead of holes. Do you know very much about that particular button? I live in central Florida and have found an item that looks just like the one you have. It is heavy, probably close to an ounce is one inch across. Was identified by another detectorist as a curtain weight, but I still think it may have been a very old button. Does the one you have match any of the description I have related. Thanks.
