Found this in the dirt with some older items that appear to be from the late 1800's - early 1900's, little glass medicine type bottles and a piece of purple glass the looks like it could be a part of a bowl or something.
It looks like it snapped off of something larger. Is that dirt in the middle or a completely rusted bolt? I’m curious whether there’s threading at the center beneath the brown.
My first thought was to stick it in acid to get a better look tomorrow, until I read “1800’s - early 1900’s”
